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,
