It should be possible to get a VGA driver - the coreboot folks are
booting on the OLPC today. Seabios adds all the "dos interrupts" - so
it shouldn't need anything from openfirmware. You will want the PIR
and ACPI tables - hopefully the next openfirmware will have that.

Linuxbios is now called coreboot.
