xorg-x11-drv-ur98 was unintentionally left out of the upstream RC1 release, so there are no driver tarballs available yet. Since this is a low priority issue, I'm logging it here for now as a reminder to build the driver when tarballs become available, or when RC2 ships. The driver packaging has been updated already in CVS, so just need to drop the tarball in place, make minor spec change, check in, and build.
The ur98 driver is in rawhide now, and updated to the RC2 version.
