How does it work? Does this means that there is no need for cooperation from i2c-core to implement I2C slave support in I2C bus drivers? Or is i2c-pxa implementing things which should be moved to i2c-core? This discussion probably belongs to a different thread though, I doesn't seem to be related to bus speed issues at all.
