This is what I found too (though lineo now seem to be metrowerks that don't
mention usb support etc). However there seems to be little or no traffic
about the chip with linux drivers (Google-able anyway) so I am concerned
that the support isn't actually there. Certainly a SL811 driver is
incorporated into 2.6 which is encouraging.

Yes but no explicit GPL'd code.

The cerf drivers are the TD drivers with no explicit copyright suggesting
one can redistribute them. Do you need a copy?

Agreed.

I'll defer to SW/DB for comments here.
