I haven't done it, but I think some of SnapGear's m68knommu/Coldfire 
uClinux targets have IDE support in them.  I don't think there's any 
rocket science, you'll just need to tweak the lowest driver level to 
talk to your interface core.

menuconfig -> kernel config -> general setup -> [X] disk hardware support

then back out to the main kernel menu, scroll down to ATA/IDE/MFM/RLL 
support - more options than you could ever hope for! :)
