I am also experiencing increased battery drain on the Telus 2.1 Rom.
I will also attempt to disable the light sensor to see if that makes any difference.

As for the startup sound just install Advanced Config 3.2 for the Diamond from Schap... you can change both the startup sound as well as the startup gif animation. If I recall correctly setting the sound to no file causes a beep at startup... so find a wav file with no sound if you don't want to hear anything.
