remove some 12 year old code that was never correct, and never compiled

anyway due to a missing #include.

the code was originally intended to handle i386 SMP EISA machines with an
IOAPIC. Since the code never was compiled, and nobody has noticed or
complained for 12 years, I think things are probably fine.
