+Subject: [PATCH] Bug 704945: Add init_device_procs entry for mem_x_device.
+
+When allocating a buffer device, we rely on an init_device_procs
+being defined for the device we are using as a prototype. Which
+device we use as a prototype depends upon the number of bits per
+pixel we are using. For bpp > 64, we use mem_x_device, which does
+not currently have an init_device_procs defined.
+
+This is a fairly hard case to tickle, as very few devices use
+more than 64 bits per pixel. The DeviceN device is one of the
+few that does, and then the problem only kicks in if the
+MaxBitmap figure is high enough (or conversely the resolution is
+low enough).
