I made a cable with the resistor. Unfortunately I had to cut right
down to the miniusb connector and open the housing to solder to the id
pin. It sort of worked to use shrinkwrap to close everything up, but
the shrinkwrap slips a little when I use the plug. I probably should
just superglue it so it won't slip.

there is an application out there... I forget the name... it makes you
play a sort of insulting game of clicking a fast-charge button several
times hidden in a field of never-mind buttons before it will kick it
in. Anyway, someone should do this right with just a single
old-fashioned confirmation dialog.
