Here, 2.4 may help. I think the PCMCIA layer has some de-bouncing
mecanism, and inb/outb should no longer cause a panic when accessing non-
existent HW. For memory-mapped devices, you may still have a problem,
which could be solved by the oops patch (in linuxppc_2_5 but not in _2_3
yet) which would cause the driver to oops rather than panic (well, in
most cases...)
