I've just been digging in the dmesg logs from when I was using the
Assabet+Neponset as my firewall, and it was having to use the IDE
ide-cs driver rather than the pata pcmcia driver.

I don't recall whether the pata pcmcia driver was a problem or not,
as the PCMCIA interface can't cope with _any_ 32-bit accesses.  I
think PATA tries to use the "highest" possible access size by
default...
