I'm very confused by the results :o/  I'm now running today's cvs
plus bsd.diff plus bsd_2.diff.  Some things work and some don't.

I can boot openbsd perfectly -- but only if I load the 'bsd' kernel
from a different filesystem e.g. FAT32.  I can't read any files from
the FFS/UFS on my openbsd partition -- I get 'outside of partition'.

I can multiboot netbsd perfectly -- but not from the netbsd partition.
If I 'multiboot /netbsd' from the netbsd partition I get 'broken magic'.
However, I can 'netbsd /netbsd' perfectly from the netbsd partition.
(See why I'm confused?)

When I 'freebsd /boot/loader' or 'freebsd /boot/kernel/kernel' from
the FreeBSD partition I get 'broken magic'.  If I 'freebsd /kernel'
from a FAT32 partition the kernel seems to load okay but then when
I 'boot' nothing prints to the console and the OS never starts.
If I 'freebsd /loader' from a FAT fs then the loader runs correctly
but of course I need to set 'currdev' by hand.

I'm wondering if you have commited all of your UFS/FFS patches to
cvs.  Seems like I'm seeing some old UFS problems that you fixed
once already(?).
