If I use 1024x768, or 1600x1200 it works, but if I try 1920x1200 (the  
native resolution) it fails.  The 1920x1200 that Xorg generates has  
too high a dot clock (limited to 150MHz) though I don't know if that's  
the problem.  So I tried a 1920x1200 Modeline that should work, but no  
go.  So I tried something like 1600x1050 and it removes it because it  
claims it can't find an appropriate modeline.  So I define a Modeline  
that should work, and again it deletes the mode, claiming it can't  
find a match.

It seems like it's ignoring any Modeline that I add to the xorg_conf  
file.

If nobody has any immediate ideas, I'll follow up with the xorg_conf  
and Xorg.log files when I can get to them.
