I liked the idea so much that I gave it a try. The patch looks much 
better now, but has the same functionality as before. As the only 
disadvantage, the patch no longer contains the template to produce a 
particular EDID. But this code may be made available elsewhere - no need 
to have it in the kernel.

Hope you like it.

Thanks,
