Unfortunately unless things have changed, depending on your hardware, no tulip
cards get interrupts delivered if you use the kernel pcmcia stuff. I have
switched back to the dhinds pcmcia package and it not only is working properly
for tulip cards, but it doesn't crash four times a day; corresponding to

With my particular laptop, I came to the conclusion that the slots were
misnumbered in the kernel driver. 0,1 was shifted one place which resulted in
slot 0 not being usable period and slot 1 could only do my ray_cs card. Unless
something has changed, I still suspect this. In the kernel code, the
tulip_interrupt() (sp?) was never even called.

Agreed. I registered precisely one interrupt in /proc/interrupts, and that
corresponded to the insertion of the card.
