You forgot the scanner on the 2940 :)

In any case, the problem sounds very much like the card simply isn't getting
its interrupts under 2.1.90. The card that is failing to get interrupts is
on IRQ 15, so who knows, maybe there is something wrong there. Try
disabling the I/O APIC code (Ingo knows how to do this, I'm not sure
although I think it's something like ioapic=0 on the boot line). See if
that helps. If not, you can always try getting the latest driver either
under 2.0.33 or 2.1.90 and seeing if it helps.
