+
+For non-PCI video devices, such as those found on many ARM embedded
+systems, the X server currently requires the BusID option to specify the
+full path to the DRM device's sysfs node in order to properly match it
+against the probed platform devices.
+
+In order to allow X to start up properly if either the BusID option was
+omitted or no configuration is present at all, the first video device is
+used by default.

+Changes in v2:
+- Add additional checks for safety (I don't think numDevs will ever be 0
+  since a default will be generated if no configuration is present, but
+  it doesn't hurt to check anyway). Without these checks there is a
+  possibility of the X server crashing if no platform devices have been
+  found.
