Please try with openchrome X driver only, don't mix with viafb. It will 
ease the debug.

Please don't use the drm-openchrome kernel, it has known issues and you 
don't need it for user mode setting anyway.
Trying either master or kms_branch should be fine though. Please note 
that kms_branch is not yet fully ready for consumption and has known 
screen corruption issue, but that shouldn't prevent X from running and 
it's still a good idea to test both.

Please provide a description of the hardware (brand, model) and setup 
(motherboard + VGA port ? laptop ? ).
Please also provide full X log.
