A snippet from http://www.linuxmafia.com/faq/Hardware/sata.html "Support is mostly in 2.6 kernels, and in circa-2.4.23 and later kernels. Note that device names will change, if you upgrade kernels from 2.4.x to 2.6.0, e.g., move from /dev/hdg to /dev/sda. So, e.g., append "root=/dev/sda3" to kernel's boot options. (According to a 2004-04-15 post to the Linux kernel mailing list, this addressing change occurs only with the ICH5 and SiI3112 chipset.)" Joe Landman wrote:

Nope not gong to happen. The drives SHOULD show up as hda/hdc(b)(Note that the second drive appears as hdc not b in my rig, probably somthing to do with the crazzy via bios...). They are just ide drives... not scsi. SATA is just a jacked up interface to ide devices. Some raid sata solutions implement scsi ontop for various reasons, this one doesn't..
All my SATA drives show up as scsi. I run a RAID0 nicely across a pair of raptors. As an FYI:
