Doing this will vastly decrease your drive throughput performance; I
tested a Dell OptiPlex 745 with SATA in "Legacy" mode with RHEL4, hdparm
reported throughput of about 3-3.5MB/s, and X was sluggish to the point
of being unusable.  RHEL5b2 works just peachy in native SATA mode, as
does using RHEL4 with a supported PCI SATA card instead of the onboard
chipset.
