What type of drive do you have? What IDE chipset do you have?
(`/sbin/lspci | grep IDE`)  I'd wager that the kernel module for the
chipset is not loaded (which would force it to revert to much slower
PIO) but near as I can tell, every IDE driver in the stock Fedora kernel
builds are static in the kernel image, only SATA stuff is built as
modules. 

Hmm. This one will be tricky to debug, methinks...
