I've got a system with ICH6 (or ICH7 maybe) controller, and a SATA disk. I don't believe it's a driver issue, and I don't think it's an fs issue, since I was dd'ing an image onto the disk, and the image contained linux partitioning and an ext2 fs. I think it has to do with the tasting (or re-tasting) of the GEOM devices, but that's pretty much a guess.
