Maybe we can add some "shoot and run" ps2 initialization code to
coreboot that runs before most other code, giving the keyboard or kbc
time to initialize while we do all the other stuff.
Have we considered threading in coreboot? It seems the time we spend in
ramstage is unsignificant and the effort of multitasking in romstage is
not worth the trouble.
