As long as the status of the PAL modes is not known, I would not commit the changes. 

I have applied Ken's patch but was unable to use any of the PAL modes he added. (According to the code only modes 640x480 and 720x576Over were added). When I set the TVType to PAL and the mode to 640x480 in xorg.conf, the X server responds that it cannot find any usable mode. Am I doing something wrong here?

By the way, the patch did not compile on my system because of the use of  '//' as a comment character. Is there a requirement on what compiler to use for the unichrome code?
