Did you recompile your test on the RHEL6 system?
On both systems I showed, I checked out a fresh copy of the PostgreSQL 9.1 HEAD from the git repo, and compiled that on the server, to make sure I was pulling in the appropriate kernel headers. I wasn't aware of exactly how the kernel sync stuff was refactored though, thanks for the concise update on that. I can do similar tests on a RHEL5 system, but not on the same hardware. Can only make my laptop boot so many operating systems at a time usefully.
