I can confirm that turning off AGP with the Omega drivers resolves the darkness issue on my Evo N610c laptop with a Mobility Radeon 7500. The heads are now visible as well, but the terrain is rather bleached out. All other settings were left alone. 1X, 2X and 4X AGP all produce the darkness issues. The gameplay, however, is so slow that the game is unplayable. I also can't leave the settings like this as general operations in Windows are severely affected (too slow) This card is specified as having hardware T&L, so I really don't see what the issue is with Firaxis calling this a hardware problem.
