My server should have that commit 
(3ec35c45ca17f5ed6fd02c50fc49ae7b8d128dcb).  I'll step through it to see 
why I'm not getting a compat_output.

I checked the callers and they all look like they'll correctly handle a 
NULL return from xf86CompatOutput, but it does also look like that's not 
supposed to actually happen.
