You would need to add them to /etc/hotplug/blacklist.  However, you should
not need to do this.

Here's the dilemma:

If these modules are not loaded, you cannot use a parallel printer.  This is
obviously not ideal for people with parallel printers.

If these modules are loaded, this seems to cause sound to fail to work on
some laptops.  This is obviously not ideal for people with these laptops.

We need to find a way to please both sides reasonably, and having to
hand-edit config files is, to say the least, suboptimal.

There is a bug open about this issue here:

It would help us to fix it if everyone who has experienced this problem
would file a comment there describing their setup, the exact problems they
encountered, and the results of attempting the workarounds mentioned there.
