GNUstep doesn't seem to be the right place for device drivers: GNUstep has to work on *nix, Windows, and even OS X. All of those have different driver APIs.
Or are you asking about writing drivers for NeXTSTEP? I don't think GNUstep would be much help there either. You'd be better off [using a virtual machine][1] to run NeXTSTEP-Intel or OPENSTEP.
