Terrific! Two questions:

- inevitably, on my TV Set (SONY KDL 3000) this now doing too much
underscan. In pixels: without your patch, I used a custom modeline to
map 1280x720p to 1220x680p, so I'm 40 pixels down in each dimension. How 
to fix that?

- more of a general drm question I guess: in what way are the connector
attributes available on the command line? I couldn't find a complete
kernel command line or modprobe invocation.

Thanks
Marius
