I've just managed to boot with PXE and 2.6.23.9 and I have come to the
following:

* softraid still works
* sata_mv is a bit slower than the proprietary highpoint drivers (I get
300MB/s from my array rather than 400MB/s)
* they array works
* the content of the array seems to have shifted 'down' a bit, that's
probably why it won't boot. 

it's a tad weird, but I can see the data just fine when I dump the
content of the drives, but it seems to be in the wrong place.

I'll recreate my volumes with sata_mv now, see if it will work like
this.
