RE: 8139too + D-Link 690 + toshiba laptop = ARGH!

And stupid me managed to fix it.

For future reference to anyone checking the archives, this message is
generated when a card is supposed to have software-set IRQ, but the driver
does not (or for some reason, cannot) set it.  The device is recognized, but
has a default IRQ of 0 which it cannot have.  The kernel tries to use it
with IRQ 0, sees a conflict and simply refuses to honor the device.  That's
why it shows up but does not function.

This means the IRQ must be set from a different resource, typically the
bios.  You will have to configure your bios to set the IRQ for you.  In my
old Toshiba, this meant switching the CardBus from auto-select to 16-bit, at
which point the bios set the IRQ for me and everything worked fine.

The D-Link card wants to use 32-bit CardBus by default so auto-select
doesn't work.  Auto-select in this case appears to mean the device does the
selecting, not the bios.  Lucky for me the card I have is backwards
compatible with 16-bit CardBus.  Your mileage may vary.
