Ok, no problem. I recompiled the kernel with libata (but without the
libata pcmcia support), and made legacy ide (only ide-core and ide-cs)
modular.
This allowed me to boot my PATA HDD with libata, and when I plugged in
the PCMCIA card it picked it up automatically with the legacy ide drivers.

At this point I noticed no /dev/hda* devices existed, so I created them
manually with mknod. But regardless I was not able to actually mount a
filesystem, getting an error from mount that the device did not exist.
When pulling the card I also got the following..
