You are doing something like an xhost +remote_host_name
before starting up the program, right? And you are doing something similar to export DISPLAY=xserver_ip_address:0.0
Dumb questions maybe, but you didn't say...
When you say "the machine that's running the client", you mean the machine whose CPU the client is primarily using (the one you started the screensaver from), not the machine whose graphics card it's using, right? You may not need the drivers over there, but I don't know for sure. It depends on whether the screensaver uses libGL or the X server does -- and I think it's the client that uses it.
