Right.

That is more or less a hack on the part of gic.

LibGII's current API currently offers no such capability, that's
the core of your problem.  Per-target mapping could be implemented,
or if you have the time, a scheme for LibGII as a whole could be 
implemented which would provide a way to access target-specific
IDs and info about the device, which is what I was referring to when 
I mentioned the mailing list discussion from some time ago.
The mailing list discussion is IIRC hyperlinked in the GII TODO
file (grep for "hash").
