I would like to see the output, next time you can get it.

The thing with the 6041 chip, is that I actually have all of the Marvell
documentation and errata info for the chip.  So in theory, we know everything
about it, and there are no secret failure modes yet to be discovered.
The sata_mv driver does not depend on the board's BIOS for anything either.

That's the theory, anyway.  :)
