That's already in my upstream kernel, here. commits
ba951841ceb7fa5b06ad48caa5270cc2ae17941e and
a3bec5c5aea0da263111c4d8f8eabc1f8560d7bf.

sata_mv and sata_nv still reliably poop themselves here, whereas its
rock solid with 2.6.23.1. Sounds like different issues from yours, as I
see a stream of SATA errors on the bad kernels, errors which are often a
symptom of something whacked in the DMA engine (misprogramming causes
the silicon to generate bogus FIS's, which the device then chokes on)
