I assume you are talking about the "GART pages must be uncacheable bug", 
which affects AMD processors.

The kernel bug is http://bugzilla.kernel.org/show_bug.cgi?id=7768, which 
has now been closed after a patch was submitted.

I searched for the commit id in the Redhat bugzilla, and found it for 
RHEL5: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=238709. That 
bug says the fix has been backported and is in RHEL5 kernel 
2.6.18-18.el5. But I don't see anything about backporting to RHEL4.
