  Xinerama is disabled in this configuration. And I use two X11 instances, on
per radeon board:

root      3322  2.0  1.3  36712 27416 tty9     Ss+  Jun01   5:40
/usr/X11R6/bin/X :0 -audit 0 -auth /usr/gnome/var/gdm/:0.Xauth vt9
root      9561  4.8  0.3  16116  8072 tty63    S<s+ 00:30   0:00
/usr/X11R6/bin/X :1 -layout x800-dualcard-e2209hds-1 -allowMouseOpenFail
-allowNonLocalXvidtune -novtswitch -sharevts vt63
