+ check from xf86CallDriverProbe
+
+If foundScreen is TRUE, then all the code below the removed if
+will not execute until we reach the return foundScreen; at the
+end, so this entire if block is redundant.

+Subject: [PATCH xserver v2 6/7] xfree86: Make adding unclaimed devices as GPU
+ devices a separate step
+
+This is primarily a preparation patch for fixing the xserver exiting with
+a "no screens found" error even though there are supported video cards,
+due to the server not recognizing any card as the primary card.
+
+This also fixes the (mostly theoretical) case of a platformBus capable
+driver adding a device as GPUscreen before a driver which only supports
+the old PCI probe method gets a chance to claim it as a normal screen.

+Subject: [PATCH xserver v2 7/7] xfree86: Try harder to find atleast 1 non GPU
+ Screen
+
+If we did not find any non GPU Screens, try again ignoring the notion
+of any video devices being the primary device. This fixes Xorg exiting
+with a "no screens found" error when using virtio-vga in a
+virtual-machine and when using a device driven by simpledrm.
+
+This is a somewhat ugly solution, but it is the best I can come up with
+without major surgery to the bus and probe code.

+Subject: [PATCH xserver 6/6] xfree86: Add ModulePath support for OutputClass
+ config Sections
+
+Allow OutputClass config snippets to modify the module-path.
+
+Note that any specified ModulePaths will be pre-pended to the normal
+ModulePath. The idea behind this is that any output hardware specific
+modules should have preference over the normal modules.
+
+One use-case for this is the nvidia binary driver, this allows a
+config snippet like this:
+
+Section "OutputClass"
+    MatchDriver "nvidia"
+    Modulepath "/usr/lib64/nvidia/modules"
+EndSection
+
+To get the nvidia glx specific glx module loaded, but only when the
+nvidia kernel driver is loaded.
+
+Together with the glvnd work done recently, this allows the nouveau
++ mesa and nvidia-binary userspace stacks to co-exist on the same
+system without any ldconfig / xorg.conf tweaking and the xserver will
+automatically do the right thing depending on which kernel driver
+(nouveau or nvidia) is loaded.
