Iīm also running SATA drives. GNU/Linux Suse from 9.1 over 9.2 to 9.3 have been smoothly installed on this system.
Running Knoppix 3.8/3.9/4.0 have no problems with finding the SATA drives. Although I didnīt install a Knoppix or Debian alike system on them.
I suggest to try a recent distro to install on your SATA drives.
You can install a GNU/Linux Suse system from ftp via the internet if you wish, or from almost any BSD-distro, such as FreeBSD, NetBSD. (No Linux, I know, but still very nice things.)
