A couple of observations.

1) When I just had the xen kernel, I installed the original non-xen kernel
using rpm -ivh, and booted to it.  This gave sadc errors on bootup.

With the newly installed normal kernel there are no longer any sadc errors
during boot.

2) I measured the frame rate for both the xen and non-xen kernels in this
laptop using glxgears.... 
For the xen kernel it was originally about 1100 fps - and when I installed
the non-xen kernel as well it reduced to about 850fps when running the
non-xen kernel.  

With the newly installed non-xen kernel after a re-install of the OS,
glxgears also gives about 850fps.
