[CentOS] Centos 5.2 and 2.6.18-92 Kernel backported SATA fixes?

Last year to get motherboards with the G33 chipset with SATA working with Centos I had to either use David Harbic fixes or use Fedora 8 since it had the later 2.6.25 kernel.

I no longer see David's fixes available and also see in the 5.2 release notes "update SATA driver and infrastructure".  Did Redhat finally incorporate fixes to full support the new G33 chipset and SATA?

I have more of these G33 chipset motherboards with Q6600 cpu.  Trying to decide which is the least hassle setup and long term i386 or x86_64, on either Centos 5.2 or Fedora 9?
