Ok, here it is... BFSpack V1.6b1 with support for Xbox and Xbox360 bfs file format (console version only, will do GUI when it's working...).
If we're lucky, they did not change format for FO:UC from Xbox360 to PC version (developpers are lazy, so there's a good chance it's the same format)....

So, basically to unpack bfs for FO:UC, you just have to do:

Hope it will work...
