The interesting thing here is that sata_mv can see the disk going off

The PSU has switched off and power to the drive was cut. I don't think
anything can go wrong at that point.
What I still find most interesting is that with 2.6.25 the extra
message(s) do not appear and the poweroff is "clean". And that it affects
2 different systems where one seems to live on just a bit longer than the
other. So it does look as if something _has_ changed.
I'll probably do a bisect to see if I can discover what/where/why...

Sure, go for it.
But I think that you will simply discover that,
the sata_mv driver now actually correctly detects/reports most errors,
which it didn't necessarily do in the past.
There were lots of EH bugfixes in sata_mv this time around.
