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. Thanks, G.
