Anyways, I've been testing pata_acpi and it doesn't work on my nforce ultra machine. Whether the cable is 40c or not, _STM happily sets UDMA mode above 2 resulting in a series of transfer errors. EH kicks in eventually and drops transfer speed. Also, ata_acpi_gtm() implementation was broken in that it skipped one level of indirection (acpi_object, please take a look at the last patch of just posted patchset), so it was basically returning garbage values. I have patches to update pata_amd to use _STM/_GTM for cable detection (a lot are taken from pata_acpi) but ACPI cable detection is just as broken as PCI config one.
