Bug 25429

Created attachment 31720 [details]
xorg log file

At startup my CRT TV connected via component no longer picks up the 576p TV Format I have specified which used to work before KMS.  Adding
the nomodeset kernel boot parameter to revert to UMS mode resolves the issue.

I have tried to use both "TV Format" and "mode" options but neither appear to work.
