grub does not understand BSD file systems

[Marius]

I have Sabayon Pro 1.1 x86_64 installed on my laptop.

Today I installed PC-BSD on a separate partition. I wanted to add to Sabayon's /boot/grub/menu.lst an entry for PC-BSD. This, however, fails. After spending some time on this, and consulting some BSD experts it seems that the problem is that the version of grub that comes with Sabayon does not support BSD file systems:

grub> geometry (hd0)
(...)
Partition num: 3, [BSD sub-partitions immediately follow]
BSD Partition num: 'a', Filesystem type unknown, partition type 0x7
BSD Partition num: 'b', Filesystem type unknown, partition type 0x7
(...)

In view of Sabayon's grub not recognizing BSD file systems, it is unable to load PC-BSD's kernel.
That is highly inconvenient. Can we do something about it?

# grub --version
grub (GNU GRUB 0.97)

There is no such thing as Sabayon Grub, grub is grub regardless of distro.

Your BSD experts should probably google a bit more http://www.gnu.org/software/grub/manual/grub.html
