[MLB-WIRELESS] Richoh RL5c475 and IRQ

Hi Craig,
I'm having a similar problem on my Abit NF7-S motherboard with the same
cradle and an Orinoco Gold card under Windows XP. I came to the conclusion
that the PCI IRQs (and lack of ISA IRQs) mean legacy PCMCIA devices wont
work, since they require ISA interrupts.
> Jul 26 10:20:49 ganesh kernel: host opts [0]: [pci only] [io 3/6/1]
[mem 3/6/1] [no pci irq] [lat 32/32] [bus 2/2]
This possibly lends weight to my theory above - the Veritech is a PCMCIA
device and needs ISA interrupts. The cradle is being fed PCI interrupt 17
(which is oddly the same one my cradle gets) but the Veritech card can't
make use of this.
PCI interrupts are new to me so I might be babbling, but it seems we've got
similar problems despite the different hardware and software?
Cheers,
Ben.
