Yes, I spotted that too. Funny on a device which is only ever 
accessed through inb/outb! 

Maybe the 0x4d0/4d1 ports can be accessed with 16 bit 
instructions, I don't know. What I know for sure is that
accessing port 0x20 with an inl/outl on some boards
locks immediately the system up (perhaps through infinite
retries).
