yes.  As usual, my time is limited.  So for the time being, it will
probably be the two different multiplexes...

Ok, that is what I was looking for.  Good. (Our original Ti firmware
image doesn't give reasonable responses, so I was worried HTC might also
give bogus replies here).

So we should actually have 'machine plugin' matching based on the
CGMI/CGMM responses.

Basically there should be a text file that contains the mapping, like

HTC	MAGICIAN	htc

which gsmd reads at startup, then issues CGMI/CGMM qureies, resolves
this to 'htc' and tries to dlopen() a machine_htc.so plugin.  This
plugin then could depend on stuff (symbols/functions) that is exported
by the vendor_ti plugin.

If you want to work in that area, I would be more than happy :)
