[regression] 2.6.23 sata_mv EH updates broke my 7042 controller

Hi,
I just pulled out my Marvell 7042 SATA controller here to give it a spin
and noticed that it no longer worked (i.e. init segvs when loading from
it), etc. 2.6.22 is fine.
Bisecting (just the file drivers/ata/sata_mv.c) resulted in
bdd4dddee325a7dce3e84cf48201a06aa8508aa4 popping out as the culprit
(file version 4537deb5e90b717a725b3d74b58b4bb1d28443d0 is fine).
Just for sanity checking: Has anyone else used 7042/6042 with the current
mainline driver?
Hardware config in my case:
Highpoint 2310 controller
PPC (big endian)
WD Raptor disk
Works fine with the other controller I've been using (SIL24), and works
fine if I revert the driver.
It also works fine if I disable the IOMMU. This would point towards
either a stale dma mapping, or a missing setup of one.
Not being much at home in the SATA drivers I could keep digging but I
figured I'd bring it up first in case it rings a bell for someone.
