I was trying the last xorg packages available (Xorg 1.10.2) with my dual PCI-E
express configuration (kernel I launch, one X11 instance per radeon

/usr/X11R6/bin/X :0 -audit 0 -auth /usr/gnome/var/gdm/:0.Xauth vt9
/usr/X11R6/bin/X :1 -layout x800-dualcard-1 -allowMouseOpenFail
-allowNonLocalXvidtune -novtswitch -sharevts vt63

The first board works flawlessly (R700), but the second crash when the first X11
operation happened, e.g.:

DISPLAY=:1.0 xset dpms force on;

I've compiled the last packages available with the exception of dri2proto-2.4.
If I compiled xorg-1.9.5 with the same packages, the secondary board in that
case works, but mesa failed.

Have you tried a dual board KMS configuration with theses last available
packages ?

Best Regards,
