Something must be sitting on these addresses or IRQs 3 and 4, or they're
trying some sort of Plug & Pray trickiness.  Check your devices.  

I know that the Award BIOS is smarter than to make these things PnP

probe fine.

Scratch the busted board theory.  You might try the 2.2-STABLE or 3.0-SNAP
boot floppy, this may be some screwy UART that has support in a newer
release.
