I really think kernel modules shouldn't be allowed to build when there 
are undefined symbols during compilation. I'm not sure if this is a 
"feature" of the kernel build system or fglrx's makefiles... I'll have a 
look if I find some time.

Regarding this specific problem, apparently these two functions were 
already no-ops in 2.6.13, so we just need to stop calling them on 
kernels that don't have them. The attached patch should do the trick, 
please test.
