Mr. Kirk, > Sounds like dmraid is grabbing them. I'm not sure where the configuration for > dmraid is, but that's a starting point. I think FC5 runs "dmraid -ay" automatically, which probes disks and sets up device-mapper configurations. However, to ensure that this is really dmraid's fault, could you post the output of "dmsetup table" after you boot the system (and before you blow away the dm devices, obviously)? If it _is_ dmraid, then you'll want to clean out any RAID configurations in the SATA BIOS, and/or run dmraid -E /dev/sdX to remove the dmraid configuration data.
