Sorry, I forgot to mention that all later kernels that I tested including 2.6.31 and the current net-2.6 also fail, so the badness comes in somewhere in between 2.6.30 and 2.6.31-rc1. I also noticed that the newer kernel allocate four interrupts for the card instead of only one, but none of them seem to get triggered, the /proc/interrupts counters all stay at zero.
