The dblquad function is only a few lines long.  I'd just copy it (and the necessary _infunc) from quadpack.py and modify them to support the limit keyword.  I don't know why that keyword isn't exposed in dblquad (I'd guess because you may want two limits and that would make a confusing interface), but since it is just calling quad(quad()), it should be quick to change things to solve your problem.

Good Luck!
