[coreboot] Coreboot patches for v2 with SeaBIOS

[Myles Watson]

Does anyone have an updated HOWTO for booting XP with SeaBIOS?  I'm
specifically wondering if there's an option we should add to v2 which
relocates BIOS tables so that SeaBIOS doesn't overwrite them, or if we
should add that to buildrom.

Thanks,
Myles
