Well, many BIOSes trigger an SMI# when doing inb/outb to the keyboard ports so 
they can emulate a PS/2 keyboard when a USB keyboard is inserted.  Do you have 
any BIOS options related to the USB legacy compat?  I know of the Nehalem 
systems I've seen they have a separate option for controlling port 60/64 
emulation which we leave disabled by default.
