Would it not be a bit more robust to have a wrapper module that pulls in
the correct one on demand? In other words, for the radeon, you would
still have the radeon.o module, but it would determine which child
module to load depending on the version of X that is requesting it. Thus
XFree86 would not require any changes and the backwards compatibility
would be maintained invisibly.
