All the upcoming drivers will be opensourced, just to avoid any doubts. This also has to be concerned about backward compatibility: http://mcentral.de/wiki/index.php/Bugtracker#i2c_dev_problem this is also a problem about the "inkernel" hybrid design, the em28xx uses the userland implementation since the current xceive reference drivers use floating point algorithms. Since those reference drivers also include sample board configurations for different boards I'll moreover use these ones and work on other things instead of reinventing the wheel.
