Pat et. al.,

I note one minor issue with updating that was resolvable:

I had been using the package xorg-x11-drv-intel-2.99.914 from 
elrepo-extras.  This package apparently isn't compatible with Xorg 1.15 
and gave a lot of hassle when trying to update.

The solution is to "yum downgrade xorg-x11-drv-intel" back to the latest 
SL package, which is now 2.99.911.  (I'd had the elrepo-extras package 
on there since 6.2 or so, when it was much newer than the SL package.)

No problems with the upgrade afterwards.
