i used a dock and it overheated my droid. on everyrom. not just sourcery. i think their are some bad docks out there. i couldnt use it because of that.
but if you have been using it without problems and now its oerheating .
use setcpu and turn the speeds while charging down. by default the phone runs at full speed while charging and maybe some roms do that automaticllly.
we didnt change anything we didnt need to to make certain functions work. we wanted it to be as source as possible.
