Yay, so that one was the PCMCIA code being broken.

This is all good. Its a PIO0 device (PCMCIA is ISA cycles which are PIO0
cycles)

The disk was found and the indentify data came out correctly.

Awww.. how to ruin a good day 8)
At this point its trying to read the partition table. It has translated
the command into a SCSI command block and into ATA,. It has queued it,
and it has just set out to issue it when it went boom
I'll do some more digging, but putting printks into ata_qc_issue_prot to
see where it explodes is the next step I suspect.
Ah, I see.. I'll be waiting. :)
