Almost right.  Facade (which I wrote) intercepts the Finder's (or anyone 
else's) _Control call to the driver to ask for the icon, and then lies to 
the caller.   Facade keeps a dictionary of icons (keyed by name), and 
points to the appropriate icon data in the dictionary depending on the
name of the volume being queried.
