   I spent quite a bit of time on this yesterday, and the results are a 
bit disturbing.  I can't promise that my analysis was perfectly 
thorough, as it was a hectic day at the museum with other volunteers 
asking me for this or that every thirty seconds or so, but it does seem 
to point to a problem.

   Both the distribution GENERIC.MP kernel and my cross-compiled one 
boot and run fine, as long as they are called "netbsd".  Booting them 
explicitly with a different filenames results in a bit of disk activity 
and then "error 5".

   Another thing that bothers me just a bit is that the kernels are of 
different sizes:

$ ls -l netbsd-*
-rwxr-xr-x 1 mcguire other 5579496 Jul  4 12:08 netbsd-GENERIC.MP-xbuild
-rwxr-xr-x 1 mcguire other 5555948 Jul  4 19:33 netbsd-GENERIC.MP
$

   The "-xbuild" kernel was cross-compiled on a 10.1 amd64 machine from 
the 10.1 syssrc.tgz set.  In light testing I've noticed no difference in 
functionality.
