I do the following:
1) Open two IDA simultaneously. One with a new dump, and the another with a known one.
2) Take an address of a function from stubs.S for a known dump.
3) Go to that address in IDA.
4) Look for function names, strings, call, etc., which could help to identify that function.
5) Search for that signs in the second IDA (with a new dump).
6) GOTO 2)
