Two things I think you should consider doing...
1) in your next post (and any bugs you open), include the `uname -a` of the last known to work correctly CentOS/RHEL kernel, and the `uname -a` of the first known to not work correctly CentOS/RHEL kernel and the respective versions of radeon &| flrgx drivers.

2) try out elrepo's el6 kernel-lt & kernel-ml and see if they work correctly for you.  I suggest this, because for me it did workaround an issue with intel chips (I guess I need to see what it will take to get the elrepo folks to make just a back-ported intel driver from 3.17 [first known to work again, 3.16 does not]) .
