I believe it is possible to add USB keyboard support to SeaBIOS without requiring SMM mode. I believe a regular usb keyboard driver will work fine.
That fails because many systems use port 0x60/0x64 as soon as they can, instead of the BIOS interface. So the system stops responding on the keyboard as soon as the keyboard driver is loaded - not very intuitive.
