I've a toshiba satellite notebook, and I tried to install centos 5.6.
The installer starts, but when it turns to graphical mode, the
backlight goes off. I see the windows, buttons, but it's very dark,
maybe the backlight switching off..
          
Ok, I rm the xorg.conf file. After I start immediately the X server, the 
screen was visible but only in 800x600 resolution.
I tried to change it, but there is no other modes available.

So I get back to console and try s-c-d, then start again X.
The backlight went off again, so I returned to the original problem.
looks like http://bugs.centos.org/view.php?id=4363 to me

I don't know if this is relevant but I do have (had?) the same problem with a HP with nvidia (+ proprietary driver); but only with the brightness set to manual. With brightness set to automatic (to environmental lighting) I don't experience the same problem.
It happened after 5.4 but since I had a workaround I didn't investigate at the moment.
