No, there isn't really a "patched" client for RHEL5 - there is only
an unpatched client.  The reason there is a separate kernel is for
servers, which are patched, and we want to allow clients mounts
on these kernels so there is a duplicate set of modules built for
the patched server kernel.  The client code used is identical.

Cheers, Andreas
