OK, thanks for the explanation. But assuming that we now instantiate the lis2lv02d device from i2c-i801 for exactly all the same machines, can't we just *enable* the freefall misc device feature of lis2lv02d and kill the dell-smo8800 driver completely? Seems more simple to maintain going forward. -- Jean Delvare SUSE L3 Support
