Ick, apparently I wasn't running what I was thought I was running. It
appears that the only reason pata_pcmcia was working at all was
because I was still using the 2.6.17-rc4-ide1 version of the patch (on
2.6.17 final). The 2.6.17-ide1 version of pata_pcmcia fails like so
(with my usual 1GB Sandisk card):
