[CentOS] Question re RHEL 5.3

I've heard now from more than one source about problems with CentOS (and RH) at least up through 5.2 w.r.t. SATA drive handling, and I've even reported on this myself in this list before.

My question is, do we have any idea if 5.3 has any improvements in this area?

One of my cohorts here, who happens to be a Fedora fan, says that these problems are fixed in F9, but I have grave concerns about putting an enterprise lifeline main application on any Fedora release. If 5.3 solves these issues, I'd much rather go with that.

Any ideas? Any places I might look to see for myself?

Thanks.
