The patch on my people's page is a *RHEL4* patch.

Just did a quick check, RHEL5.1 gfs-kmod-0.1.19 should have this patch 
and will be released *very soon*. Mind to wait for a little bit longer 
to get an "official" version ? Or go to our cvs (which is open to 
everyone) to extract the source yourself ?
