googling around with some of the filenames as string, I came across what seems to be a developer forum for chinese firmwares and the like. google did a surprisingly good job at translating those pages into human language :P, so give it a try... you might find some useful information there...

This actually seems to be the firmware-updater-heaven! only catch (big one) is that you cannot download anything, or register into the forums... at least I couldn't.
Somehow, I got to see a Vssver.scc file, and that seems to be a tool used to maintain/distribute the fw source code among different developers. that's a visual source safe file, which is a windows tool... although all the binary files seem to be made using some sort of unix system, not sure. hope it helps any programmer/programmer-wanna-be out there.
cheers!
