 This one should be fixed in X.Org r6.8.0, with the patch attached, which
 is also at http://people.freebsd.org/~anholt/X/patch-mga-mystique.diff
 (for your whitespace pleasure)
 
 Just drop it in your x11-servers/xorg-server/files directory and
 recompile.  If this fixes it, I might commit it during the slush.
