I found the following "hack" works perfectly for me:
(Assuming you're stuck in "Discrete" mode in gfxCardStatus)
1) Open the Activity Monitor
2) Search for "Little Snitch Network Monitor"
3) Force Quit it (When it quits, it will re-open immediately, but without being a gfxCardStatus "dependancy")
4) Change your gfxCardStatus to "Integrated"
I've been doing this multiple times a day when I need to manually switch between GPUs, and I've noticed no side-effects to the operation of LS.
