[PATCH] radeonfb update 

It adds the sleep support for newer powermacs, improve power saving on some
laptops, makes use of the new fbdev modelist management routines, and fixes
a few backlight related issues.

I tested it on a thinkpad T30 and a few PPC boxes with success.  It should
be less invasive than the previous one (I don't try to restore the mode on
exit, that is what breaks the thinkpad and possibly other stuffs that boot
in VGA text mode), plus fixed a couple of bugs in the mode detection code. 
I also reverted the memory map fix on ppc since it doesn't work properly on
some recent laptops where the firmware sets a tiled display.  I'll rework
that completely to update the memory map as part of the mode setting later.
That should fix various issues when switching with X/DRI on x86.
