So I suppose I put my driver hacking attempts on the back burner for now and wait for that mmc framework to be designed? I still wonder why I cannot really talk with the chip in my notebook, though. Maybe one day someone crafts a driver for it where I can see how it's done the right way... Best wishes, Thiemo -- Query a PGP key server (e.g. http://www.pgp.net/) for my public key 41068629.
