The OLPC port of GRUB is mostly complete now.  There's a problem with
finding the boot drive though (I'm working on that atm).  Other details
at http://grub.enbug.org/OLPC

As for the BIOS dependency, GRUB 2 is very portable so it wasn't a problem
(we used the existing keyboard driver from the Coreboot port, and the OFW
client framework we already had for powerpc).

Some might find it practical to have the GRUB menu & update-grub to autobuild
it :-)
