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.
