Just to confirm a working set-up with a 3Gbps capable
drive on the TX2plus: The drive is not jumpered to
limit itself to 1.5Gbps (it can do so), but still works
flawlessly on the controller. Here's the relevant part
of the dmesg (out of 2.6.20):

The two IDE drives also work flawlessly (with your patchset to support them backported
from 2.6.21git).

The drive (Samsung HD401LJ) btw fails to be detected by the sata_via driver
in 3Gpbs default setup. It has to be jumpered to 1.5Gbps on that controller.
On the TX2plus it works without limiting (but still at 1.5 as you can see, which
as far as I know is the controllers hard limitation anyhow).
