By that point I was desperate. :)

I think ide3 is quartenary(sp). ide0 is primary, ide1 is secondary, ide2
tertiary, and ide3 is the fourth.

I got it working this morning, though. Basically, I changed the card
settings to some odd ones (odd according to the PnP Manager, not that I
trust it), and it booted fine. Someone mailed me and told me to look at
/proc/ioports -- I wish I'd known about that one sooner. Seems that Linux
allocates those addresses for a serial driver.

Oops. :) So the problem wasn't the kernel, but my ignorance of the
diagnostic capabilities of the /proc filesystem. :)

I thank everyone for all the help.
