I'd suggest first testing a newer kernel. That one is pretty ancient
by now. The RHEL4.6 kernel contains a much more updated CIFS version
and this may "just work" there. If it still doesn't work with that,
then I'd suggest testing the kernels on my RH people page:

http://people.redhat.com/jlayton

...finally, if that doesn't help then open a RH support case
(preferably) or a RHBZ case directly and I'll have a look when I can.
