Following up, the gnome power settings workaround helped slightly, but I still got lots of crashes and unsuspend failures. I did end up going w/ 32 bit Ubuntu 11.04 + nVidia binary driver and things are working quite smoothly now, albeit with 1/2 the bits :-P

Changing the brightness works great after I add

Option "RegistryDwords" "EnableBrightnessControl=1"

under the "Device" section of my xorg.conf.

So who knows why this works fine in 32 bit-ville but not 64?
