I don't claim to know all the details of how this hardware works, but I do know that you _cannot_ share the IRQ between the pcmcia bridge and the pcmcia card and that the pcmcia card certainly can use other IRQs; pcic0: <Intel i82365> at port 0x3e0 iomem 0xd0000 irq 10 on isa0 pcic0: management irq 10 pccard0: <PC Card bus -- kludge version> on pcic0 wi0: <WaveLAN/IEEE 802.11> at port 0x240-0x27f irq 5 slot 0 on pccard0 wi0: Ethernet address: 00:60:1d:f0:d8:63 This configuration works perfectly for my laptop and is how I've set up a dozen other machines.
