I've had the same problem with my 760ED, whenever I try using a Cardbus
card (PCMCIA cards work OK). Always `no IRQ known for interrupt pin',
and the message about pci=biosirq, and no improvement (but no kernel
panic) despite trying all possible parameters for pci=foo. I also found
exactly no difference was made by switching between built-in kernel
drivers and pcmcia-cs. I haven't tried anything more recent than
version 3.2.2, though.
