Since the upgrade to fc12 alpha my built-in webcam isn't turned off default. I see this by a green led built into my laptop.

Your webcam is a UVC cam, so the LED is controlled by the firmware inside the webcam. In older Fedora versions hal used to open and close the cam to probe it during boot, there by probably turning the LED off (like running cheese does). We've stopped doing this probing, but your webcam firmware really should just start with the LED off.
