LCD Backlight Brightness Control on T61
To the best of my knowledge, no one has been able to get lcd backlight brightness control to work with this video card on the T61 when using the proprietary driver. However, brightness control works fine when using the vesa driver, so it seems that the problem lies with the Nvidia driver itself.
Strangely, if the nvidia module is loaded with the argument NVreg_EnableBrightnessControl=1, one can switch to a virtual console, change the lcd brightness level there, and have that level preserved after switching back to the X session. This was tested with the acpi video driver included in the vanilla Linux 2.6.21-6 kernel.
