It could be that RHEL may have a more conservative configuration (eg. no
DRI). Are you able to copy across the config from the Ubuntu/SLES install
and try that under RHEL?
Any differences between them may well show up a workaround/solution; or
otherwise we can start patch hunting.
BTW, could you report the fact that you think it's fixed in the RH release
to the upstream FD.org bugzilla---that may give them clues too, and they're
in a much better position to follow that up directly.
