I'm having issues with it recognizing my CD-ROM drive and applying 
updates. (I'm not happy with FC8 right now.)

The module should not have any external dependencies.
(However, see note below about pulseaudio.)

Fedora 7 and 8 are known to have broken sound:

Fedora 9 is supposed to fix the sound, but the release is 13 May.

I'm not sure having somebody new to Linux edit a .perms file is a good 
way to start them off. (Maybe use an install script to do it.)

Here is the bug report...

This is how to modify the .perms file:

Most people like Ubuntu because it works with almost any hardware.

I'm guessing, all /dev/snd devices in FC8 are root,root because 
everything goes through pulseaudio:
