Does this work with normal PCs?  I'm pretty sure the basic bell thing is a 
single fixed amplitude TTL signal from the IBM XT days of yore.  (I guess you 
could use PWM to simulate a reduced amplitude given the inertia of the 
speaker coil even so... hm)

Modern audio chipsets take in the TTL-level bell and allow it to be attenuated 
with a volume control, but is it true that X really knows how to do this?  It 
doesn't touch audio in any other way AFAIK (which may not be far enough!).
