can someone point me at a thread that explains why being able to
configure one's system to ignore a device is so plainly wrong? 
i'm clearly missing something.

and, conversely, can someone perhaps tell me why the currently
documented (and clearly at least partially implemented) option
that should let me ignore a device doesn't seem to work?  (my
need for this feature is temporary -- hopefully by the time it's
deprecated in a released udev, similar functionality will have
been recreated (!) in devkit-power, or the XO's need will have
gone away.)
