commit 95991fcce45f0dd904f76b9f98f9c7ed5708e4fa
Author: Michel Dänzer <michel.daenzer at amd.com>

Bail if we're trying to start up in UMS mode on KMS.
Ideally, the display manager will start the X server again, and everything
will be fine and dandy. But in the worst case, at least we won't hit the
hardware behind the KMS driver's back.
(This change intentionally makes (ab)use of the fact that Bool is defined as
int).
