Adjust Screen Brightness from Terminal

This blog post discusses has a small commandline tool (written by Nicholas Riley) to set the brightness from Terminal. Just download the binary [4KB] and install it. You can then set the brightness by typingbrightness 0 (to set it to minimum, use 1 for maximum, or any value between).

Note: The binary is Intel-Only (32-Bit), but the source code is available on the above linked page too, so you could easily compile a PowerPC or 64Bit Intel Binary on you
