Not sure if you know this but there should be no speed negotiation/DMA
level issues with a native AHCI SATA implementation.  If its reported
as SATA-150, its probably a hardware issue (with FPDMA and the general
DMA architecture of SATA, the driver really has no clue nor should it
on what speed the bus speed is - its strictly up to your cable,
chipset and drive).

I would definitely check what Jeremy mentioned as well as a faulty cable!

Long live no more CS jumpers....
