I wondered if it might be.  It's a real pain not having the X server 
working - I'd like to make my Cats board into my main X console (since it

Hm, interesting.  Yes these could all be related.

I'll have a poke around, the shark has always had ISA interrupts, so maybe 
that will provide a clue...
