Thats what I thought, nice to have it confirmed though. The port mapping should be fixed, so the pcmcia driver
most likely suffers from some API change. Before we created a "junk" IRQ by setting irq_desc[].chip = &blabla_type,
Im guessing the irq_desc now requires an actual interrupt action now.

I tried it and it didn't do anything, so you are quite correct.

Thanx for feedback
