The first step would be to look at the output of dmesg to see what actual 
problem is reported. The kernel is not tolerant of just any module, and 
building modules outside the tree is quite complicated. It will probably take 
less time if you get the Fedora source, adjust the configuration, and rebuild 
the kernel. Otherwise, you will need to prepare the special makefile needed for 
building outside the kernel.

For modules.dep to be updated, you need to copy the appropriate modules into the 
/lib/modules/`uname -r`/ directory tree, and then run the command 'depmod -a'.

As I do not use Fedora, I was not aware of Fusion. Perhaps you could get them to 
reinstate this driver in their package. In addition, you might post a bug at 
Redhat in hopes that they will change their standard configuration. As a last 
resort, you could switch to a distro that includes this driver in their standard 
kernels.
