It's time for a week long party!

It works great, interrupts are even delivered to the tulip handler :)

Attached is the boot dmesg in case any aesthetic changes are desired.

Ted, please scratch off the NEC Versa LX PCMCIA entries as fixed, I assume this patch will go in on the
next release.

MEGA thank yous,
