Both command-based and FIS-based switching seem to work just fine.
But there is a problem, maybe you could help with ?

I've just noticed that, if I unplug/replug the host-side SATA cable
on the Sil3726 PM, and *then* "insmod sata_mv", the PM is not found.

If I then simply do "rmmod sata_mv ; insmod sata_mv", then the PM is found.

This happens with the original hardreset code from Jeff,
as well as the updated sata_mv code that I've posted earlier.
So it is not anything I've broken (recently :) ).

Very strange.. I wonder if it also happens with the Marvell PM,
except I don't have one here to test with at the moment.

Ever heard of anything strange like that?
