this doesn't sound very promising.... :-/ for my part, i only figured it
out how to setup with the help of detailed descriptions from the
ubuntu-wikis and -forums.

since this topic seems not to be the easiest one, i would even be glad
to hear some succes stories:

is anyone from that list using gem successfully on a system with
installed fglrx-driver? i really hope, there are many gem-on-linux users
around, so there is still hope :-)
