Just FYI:

(1) There is working cross toolchain for i386:
ftp://ftp.netbsd.org/pub/NetBSD/misc/fredette/hp700/cross-hppa-netbsd-1.1.0.1.tgz
    (you can use it by pkg_add(1) on i386)

    arch/stand/mkboot can compile on i386 as a host tool (fixed by chuq),
    so I think you can still try pre-SA (prior 1.6P) kernel.

(2) I tried to fix gcc-3.3_branch but it stuck. (non-working patch attached)
    Maybe we should not use dbxelf.h and elfos.h, but not sure.

(3) Diskless NetBSD How-to for hp700 is quite enough:
http://www.netbsd.org/Documentation/network/netboot/intro.hp700.html

    For some newer machines (like 712/60) requires dhcpd patch:
http://mail-index.netbsd.org/port-hp700/2002/03/04/0000.html
    but I don't know it is fixed the recent dhcp in -current.

(4) When I checked osiop(4) and oosiop(4) on hp700 (with 1.6P sources),
    it seems there are some pmap/vm bugs. I've filed one of them
    (port-hppa/20933) and physio works fine with the patch, but
    executing binaries on disks still has some problem.

etc. etc.
