Nice machine.

Yes. In fact, polling mode is the only way that multiple pcics work
today. At least that's the only way how I've been able to make them
work.

Hmmm, I've not hit a machine that needs that many. The right solution
is to teach the pccard system to share interrupts amoung itself, but
that's hard to get right.
