I have a single GridSeed on the way and I want to run it on my 5 GPU Debian system. It's currently running sgminer for the GPU's and I'd like to keep that way. What is the process I'd use to get your modified cgminer working with the GridSeed?

Would this theoretically work?

Plug in GridSeed into power and USB
git clone https://github.com/dtbartle/cgminer-gc3355
cd cgminer-gc3355
./configure --enable-scrypt --enable-gridseed
make
./cgminer -o: (url) -u (user) -p (password) --griseed-options=freq=850

Would it try to use my GPU's? How would I tell it to use the GridSeed only?
