Yes, that would be nice. Although I seem to remember that there were already
differences. Like -a or -b for "askroot"?
loadbsd.c 3.3 source attached, in case you want to try it. :)

* Version history:
* 1.x Kernel startup interface version check.
* 2.0 Added symbol table end address and symbol table support.
* 2.1 03/23/94 - Round up end of fastram segment.
* Check fastram segment size for minimum of 2M.
* Use largest segment of highest priority if -p option.
* Print out fastram size in KB if not a multiple of MB.
* 2.2 03/24/94 - Zero out all unused registers.
* Started version history comment.
* 2.3 04/26/94 - Added -D option to enter debugger on boot.
* 2.4 04/30/94 - Cpuid includes base machine type.
* Also check if CPU is capable of running NetBSD.
* 2.5 05/17/94 - Add check for "A3000 bonus".
* 2.6 06/05/94 - Added -c option to override machine type.
* 2.7 06/15/94 - Pass E clock frequency.
* 2.8 06/22/94 - Fix supervisor stack usage.
* 2.9 06/26/94 - Use PAL flag for E clock freq on pre 2.0 WB
* Added AGA enable parameter
* 2.10 12/22/94 - Use FindResident() & OpenResource() for machine
* type detection.
* Add -n flag & option for non-contiguous memory.
* 01/28/95 - Corrected -n on usage & help messages.
* 2.11 03/12/95 - Check kernel size against chip memory size.
* 2.12 11/11/95 - Add -I option to inhibit synchronous transfer
* 11/12/95 - New kernel startup interface version - to
* support loading kernel image to fastmem rather than chipmem.
* 2.13 04/15/96 - Direct load to fastmem.
* Add -Z flag to force chipmem load.
* Moved test mode exit to later - kernel image is created
* and startup interface version checked in test mode.
* Add -s flag for compatibility to bootblock loader.
* 05/02/96 - Add a maximum startup interface version level
* to allow future kernel compatibility.
* 2.14 06/26/96 is - Add first version of kludges needed to
* boot on DraCos. This can probably be done a bit more cleanly
* using TTRs, but it works for now.
* 2.15 07/28/96 is - Add first version of kludges needed to
* get FusionForty kickrom'd memory back. Hope this doesn't
* break anything else.
* 2.16 07/08/00 - Added bootverbose support.
* 01/15/03 - Plugged resource leaks.
* Fixed printf() statements.
* Ansified.
* 3.0 01/16/03 - ELF support through loadfile() interface.
* 3.1 07/10/11 - Added a serial console flag
* 11/18/15 - (gnikl) Added detection of A600.
* Fix handling of multiple -n options.
* 3.2 09/02/22 - Make it compile with modern AmigaOS gcc ports.
* 3.3 01/04/22 - Loading the kernel to the highest priority memory
* segment is the default now. New option -l to revert to the
* previous behaviour of largest segment.
* New option -M to define a minimum size for the memory segment.

NAME\n\
\t%s - loads NetBSD from amiga dos.\n\
SYNOPSIS\n\
\t%s [-abhklpstACDSVZ] [-c machine] [-m size] [-M size] [-n mode] [-I sync-inhibit] kernel\n\
OPTIONS\n\
\t-a Boot up to multiuser mode.\n\
\t-A Use AGA display mode, if available.\n\
\t-b Ask for which root device.\n\
\t It is possible to have multiple roots and choose between them.\n\
\t-c Set machine type. [e.g 3000; use 32000+N for DraCo rev. N]\n\
\t-C Use Serial Console.\n\
\t-D Enter debugger\n\
\t-h This help message.\n\
\t-I Inhibit sync negotiation. Option value is bit-encoded targets.\n\
\t-k Reserve the first 4M of fast mem [Some one else\n\
\t is going to have to answer what that it is used for].\n\
\t-l Use the largest memory segment for loading the kernel.\n\
\t-m Tweak amount of available memory, for finding minimum amount\n\
\t of memory required to run. Sets fastmem size to specified\n\
\t size in Kbytes.\n\
\t-M Request a minimum size in Mbytes for the kernel's memory\n\
\t segment. Defaults to 2M.\n\
\t-n Enable multiple non-contiguous memory: value = 0 (disabled),\n\
\t 1 (two segments), 2 (all avail segments), 3 (same as 2?).\n\
\t-p Use highest priority fastmem segment for loading the kernel.\n\
\t This is the default.\n\
\t-q Boot up in quiet mode.\n\
\t-s Boot up in singleuser mode (default).\n\
\t-S Include kernel symbol table.\n\
\t-t This is a *test* option. It prints out the memory\n\
\t list information being passed to the kernel and also\n\
\t exits without actually starting NetBSD.\n\
\t-v Boot up in verbose mode.\n\
\t-V Version of loadbsd program.\n\
\t-Z Force kernel load to chipmem.\n\
HISTORY\n\
\tThis version supports Kernel version 720 +\n",
