I found the `beep' module to be perfect for this:


It redirects all system beeps to a fifo in /proc/ , and you then leave a daemon
listening on the other end of this fifo.  This daemon can be configured to play
any noise, at any given volume, whenever the kernel wants to make a beep.

Disclaimer:  Not for the faint-hearted.  Requires a small patch to the kernel,
and also some debug commenting out.
