What would be awesome is if video chips dynamically added an entry for the 
EDID native mode in their VESA BIOS. For my notebook (ATI X1400), I am 
lucky that the native panel resolution is in the BIOS list, but my external 
monitor has 1920x1200, and that is not listed.

What may also work for most of us is if we could create video drivers for 
some modern chips that only allow mode switching. No other accelerated 
functions would need to be supported. Then the app_server could use the 
frame buffer like it does in VESA mode, which appears to be even faster for 
most modern computers, at least when any compositing is involved. (That 
being said, I do still have a few ideas how to make that faster when using 
the real frame buffer as back buffer with native drivers.)

Someone could for example take the new ATI Radeon specs and write a driver 
that only supports mode switching and don't bother about other accelerated 
functions. Whoever does that wins 1 week vacation in the beautiful city of 
Rostock at the Baltic Sea. (Make sure the driver supports X1400, though!)
