Mplayer lets you specify the Xv port, so I can exercise both the 
Textured Video Adapter or the Overlay Adaptor from the command line. 
Both work for me. I can set brightness/contrast/saturation with the 
Overlay. With textured it reports descriptors for brightness/contrast 
but they are not actually implemented (as Keith mentioned).

The two it was getting wrong for me were VideoRam and CacheLines, I 
worked around it with

   Option        "CacheLines"    "512"
   VideoRam      65536

in Xorg.conf.

I'm still stuck on getting anything other than the 3 generic resolutions.

Does my log


shed any light?
