Default Init files and removing apps

A lot of work has gone into removing AT&T Bloatware, but has anyone looked at the init files to see what/where some of them are auto-starting?

Have the init files been changed in any of the custom roms? I ask only because I wonder if the OS will keep trying to start something that is not there? AT&T Navigator seems to be one of those apps that runs on its own, so i wonder if it starts in init.rc?
