My Doom 3 autoexec.cfg file, optimised for nVidia 7800GS/T on PowerMac G4. Sorry about the inclusion of all of my settings - the original file (which was lovely and neat) has been munged by Doom! Just change the keys from the menu.

Some little AppleScript-based programs, which you can use to turn enable or disable nap mode, or switch between single and dual processors. Handy in your Startup Items!
