Unfortunately, the ATAPI on SATA patches haven't yet made it into the  
kernel, they depend on quite a few things that aren't yet stable  
enough to merge. If you really need to use the drive ASAP I suggest  
you try to roll your own kernel using Jeff Garzik's libata-dev kernel  
branch, or even a recent -mm kernel like 2.6.14-rc4-mm1, which might  
help get the drive working...

Good luck!
Chris

PS: SATA might "suck" compared to SCSI, but it sure beats PATA!
