You're right. The IBM trackpoints unfortunately don't have a 'native' mode, they always do full processing and send classic PS/2 packets.
I think we shouldn't need a handler, since we can use the PS/2 protocol one. We'll need some options to set the trackpoint tap behavior (as far as I know it can only be mapped to a button), and we'll need a safe detection, but that's all. -- Vojtech Pavlik SuSE Labs, SuSE CR - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
