It may not be the ata_piix driver -- I set my controller to AHCI mode before I even installed Jaunty, yet I experienced filesystem corruption. My corruption could have been caused by an unrelated bug, however.
I haven't had any problems since I upgraded to a backported Karmic kernel. If anyone else wants to try the Karmic kernel, you can get it from my PPA at <https://launchpad.net/~a7x/+archive/kbp>. I will try to keep it up-to-date as newer versions of the Karmic kernel are released.
