I'm still sorry to report again that the SPI/I2C code is missing because it is not implemented in current io, i.e. this driver cannot work as is. For just this single driver you could add access to SPI/I2C directly but that's what has to be done about it (I think). Adam -- Adam [email protected] Lackorzynski http://os.inf.tu-dresden.de/~adam/
