Wrong BIOS is pretty fundamental -- the BIOS could have messed up many
undocumented (and possibly write-once) register settings etc. The
kernel can work around slighly broken ACPI tables or things like that,
but if, say, undocumented write-only north bridge registers are wrong,
not much we can do about that.
Really you better just get the right BIOS on the board.
