  I don't install them. :-)

  I'm actually fairly unfamiliar with the details of managing/administering 
Linux systems so I'm guessing that there are much better ways of controlling for 
which devices a Linux system will attempt to load drivers.  For instance, I 
didn't know about the concept of "blacklisting" a driver.
