I plan to reinstall the 5750 card in the morning.  This time, if I get 
black screens again, I will use SSH to obtain 'dmesg' and 'Xorg.0.log' 
output.

Does the kernel DRM take advantage of kernel debugging features at all? 
  Would passing kernel parameters such as "debug" and "initcall_debug" 
be of any value?  Or any other options.

What about debugging options in xorg.conf?  I traditionally use 
"ModeDebug," but don't really know of anything that might be more useful 
in xorg.conf.
