Sorry, I gave you incomplete information.  I can use 'multiboot' to load
the netbsd from any kind of fs, but it makes no difference:  'boot' then
causes the machine to reboot instantly.  The same applies to aout:  I
can aout load from any fs, but then 'boot' make the machine hang.  The
type of fs makes no difference.

I can still 'chainload +1' or 'linux' successfully.

All of the above applies to the latest grub2 from cvs with your most
recent ufs and aout patches applied.
