Hi Charlie,

Michael Tokarew recommended the same already and Ben has success,
but what seems strange to me is that two cards claimed to be identically
come up with different subsystem IDs, else card=99,99 should work too ;)
The also different gpio init might not indicate much, if not after boot
up.

Cheers,
Hermann
