There have been some patches some time ago for FreeBSD (IIRC), but
consider that at the moment the *BSD are not _natively_ supported. This
means that you can not have GRUB booting _directly_ the kernel. But GRUB
can chainload the bootloaders of the *BSD.
The distinction here is that, for example, OpenBSD bootloader can not
give you a choice to boot something else than its own stuff. You need
another bootloader to have the choice --- say GRUB. So when you install
a *BSD _don't install the bootloader on the mbr_: the installation will
install a sector at the beginning of the 'a' slice of the portion of a
disk devoted to *BSD. Once this is done, you can tell GRUB to chainload
this sector. If the a slice is on the 4th primary partition of the first
disk, the two lines:
root (hd0,3,a)
chainloader +1
will give control to the BSD bootloader.
For general infos, make a search on Google or others for multiboot. I'm
sure there are howtos even if I have no URL at hand.
