Hum... interesting. I had seen reports of this before, but they were of
the variety "drivers/ide has high load, libata doesn't". So it seems
intrinsic of the hardware, which is a useful data point.
Have you tried messing around with interrupt routing in BIOS setup?
Since ATA, USB, and eth0 are all on the same interrupt, changing that
may affect the situation positively.
