I thought that there was a linux version of geepee at firefly's page?
Anyways, I see what you want to do: Run linux on the GP32, then run GeePee on that, running linux, running GeePee.... So you have infinity emulators running on your GP32 at once!!!
Unfortunatly the linux version is quite old and buggy compared to the latest windows release. I've sometimes had more success using the windows version through wine.
