I can confirm. however, that the BIOS is set to Auto / LBA and that BIOS confirms UDMA 5 is set (and cannot be set unless the correct cabling is detected).

Andre is the one to say if the driver is compatible. I can't find a single reference to the 80821 in drivers/block/*.c for 2.2.19pre17 + ide.2.2.18.1221. Here's what a PIIX4 looks like.
