Have you checked the jumper settings on the drive? There may be a jumper 
forcing SATA150 mode on the drive. I'd reset everything to factory 
defaults if possible.

You might be able to use the ata driver from 7.0-R in -stable to boot your 
system. If that works, try searching for the commit that breaks your 
controller.
