Okay, first with the original non-patched 1.98 grub2 version,
after setting the type to 4.2BSD in bsdlabel:
phenom# bsdlabel /dev/md5555s1
# /dev/md5555s1:
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
a: 48116 16 4.2BSD 0 0 0
c: 48132 0 unused 0 0 # "raw" part, don't edit
phenom# newfs /dev/md5555s1a
/dev/md5555s1a: 23.5MB (48116 sectors) block size 16384, fragment size 2048
using 4 cylinder groups of 5.88MB, 376 blks, 768 inodes.
super-block backups (for fsck -b #) at:
160, 12192, 24224, 36256
phenom# mount /dev/md5555s1a /mnt
phenom# grub-install --root-directory=/mnt --modules=ufs2 /dev/md5555
/usr/local/sbin/grub-probe: error: unknown filesystem.
Installation finished. No error reported.
This copies /boot/grub/* to /mnt as before. Now, if I run qemu, I get
dropped into grub-rescue:
% qemu -hda bsddisk.img
GRUB loading.
Welcome to GRUB!
error: unknown filesystem.

Unfortunately, the patch doesn't apply cleanly (against the
bzr version):
% patch -p0 < ../../patch-002
Hmm... Looks like a unified diff to me...
The text leading up to this was:

Any idea?
