Well, BIOSes these days are all the same anyway (Award/Phoenix), and no one gives a fk about BIOS code safety. Even the "anti-thievery" measure of permanent security codes (unlockable by manufacturer only) is moot, as you can reverse-engineer BIOS updates and get the code from them.
And I would not rely on BIOS code be security-audited in ANY way! Especially not the part of the code dealing with USB. Low-level as it may be, I bet there exist buffer overflow or other vulnerabilities in USB protocol stacks.
