Oh crap. I did test it a couple of months ago, but my boot/root drive
is libata not IDE -- so no panic on boot with it. After booting, it worked
just fine talking to PC-CARD CF devices using the polling.

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..
