Those are the SATA settings.  Which modes does it have?

I have VERY bad experience with any combined mode.  Enhanced/Native
works for me.  But I only have an ICH5R south bridge, which has id
8086:24d1 (in native mode at least).

Hmm, yeah the ICH7 is rather new.

It is listed in sata_piix in 2.6.12, so perhaps doing 'modprobe
sata_piix' on console2 with the 2.6.12 install image would actually find
it in native mode.  The discover data is not changed in my 2.6.12 image
so it won't auto detect any of the new hardware that it can actually
run, but at least the drivers are present.

Otherwise ide-generic is likely to be running it in combined mode and
that would give about 3M/s.

Certainly would.
