But, it is worth reporting that brightness controls do work with Intel.  I 
almost fell out of my chair in excitement.

I read a rumor that it is the Intel graphics card that controls the brightness 
always, even when Nvidia is enabled.  So if Intel is working now then maybe 
getting brightness with Nvidia is just a keyboard mapping issue.

I believe this is a hardware issue.  HDMI is only wired to the Nvidia.  VGA 
output is wired to both.  Maybe others can confirm.

I tried suspend with the live CD and everything seemed to come back on resume 
(though I had to press a brightness key to get the LCD to light up).  However, 
I also had some major filesystem I/O issues on resume.  But this could be just 
a peculiarity with the live CD and some ramfs mounting problem.
