Tried that just now, ide_generic doesn't get loaded, amd74xx gets
loaded instead, still have all the same problems (seems to indicate a
hardware problem, however, the BIOS settings check out, the cable is a
brand new 80 wire, and the system worked well under Hoary).

A couple thousand Mb/s on -T (cached) and between 500k/s and 1Mb/s on
-t (buffered).  Playing around with the various settings like multiple
block reading (between 0 and 16), unmask IRQ, 32/16bit, etc can get me
up to about 2Mb/s sometimes...  still horrible.

I'm going to try replacing the cable, but I seriously doubt it's
hardware-related...  the system's been running great for a few months.
