I've posted a more comprehensive patch for this which allows
compat_output to point at any output and deals with missing crtc or
randr_crtc elements. It's on the compat_output branch in the server main

Testing and review welcome; Eric Anholt has tested it and found that it
fixes a known crash in his environment, so we're getting somewhere at least.
