How to set system to use graphics driver of first phase of 13.1 32-bit KDE installation?

Upgrading the whole X stack did indeed help. Switching to the X11:XOrg repo changed 119 packages. I #'d all the lines in 50-device.conf file and rebooted. It did boot into graphics using the savage driver. The graphics were flaky, so I edited the 50-device.conf file to be

Section "Device"
  Identifier "Default Device"
  Driver "savage"
  Option "NoAccel" "true"
EndSection

and rebooted. Graphics are running satisfactorily now. I’ll go comment in the bug report. Thanks for all the help.
