Right, 2nd-gen 3Gbps chips have had "intermittent" issues,
which we hope are cured by the recent ASIC bug workaround,
but it will take a while for that fix to propagate out.
To speed up that process I'm considering backporting the fix
to 2.6.23 and 2.6.22.
NCQ and PMP are supported in the hardware and in the vendor's
driver, but not yet in sata_promise. My intention is to add
NCQ soon, but there's no time-plan yet for this.

Backporting would be nice, since we're still some ways from a stable
2.6.24, and I'm not comfortable running -rc kernels in production
enviroments.
