I'm UP. Applied the patch, and the only difference I've noticed
is that some files in /proc/ide/ide0/hda were truncated. Viz.
settings, identify, smart_thresholds, smart_values. (Were ok
before the patch.)

I have a TXPro motherboard and, before and after the patch, the
driver apparently can't correctly initialize the controller.
