Interesting. This is the fglrx module trying to use an internal symbol
in the kernel that kernel developers have marked as "GPL only", that is,
that it should only be used by GPL licensed modules. Not much can be
done other than changing the kernel to accept that symbol lookup, I
don't know if I would do that (apparently fglrx should not do what it is
