Yes, my patch only improved the error reporting, not the underlying problem 
of a too old version of e2fsprogs. Nevertheless FC5 has an appropriate 
version of e2fsprogs (as well as FC4 btw.).

So your problem is a different problem. As Andrej noted in the other mail, 
disabling SELinux might help. I remember reading about this already on one 
of these lists here.

Just for the archives or anyone using pygrub on RHEL4/CentOS4: I have 
successfully rebuilt and used e2fsprogs from FC4 on RHEL4/CentOS4 and have 
had no issues so far. YMMV. (Don't forget to rebuild pygrub after 
installing the new e2fsprogs!)
