Are you sure you did not also have a change from/to Xen at one point in the system's life?

i.e.  /etc/sysconfig/kernel
has
DEFAULTKERNEL=kernel-xen
instead of
DEFAULTKERNEL=kernel

or
UPDATEDEFAULT=no

????
I ask because for me it was a system that had once _been_ xen, and was not anymore, which kept
hanging on to old kernels, Really embarrassingly old kernels [ which fully proved to me that yum
will not replace the running kernel ].

And I have never had a problem getting rid of rhgb, which I do on all most all machines I admin.
