Hello,

I am assuming that if the inertouch message is not showing up in dmesg,
then it is working. Is that a correct assumption?

Either way I also attached my dmesg.

I am not sure, though, why the scroll mode still freezes if I move the my
fingers quickly on the touchpad while also using the trackpoint. Is that
maybe a future fix and this change is just the foundation for it? Overall
the usage of the trackpoint is better now for sure.

Sadly, you are also hit by:
[    6.355378] i801_smbus 0000:00:1f.4: BIOS is accessing SMBus registers
[    6.355380] i801_smbus 0000:00:1f.4: Driver SMBus register access inhibited

Which disables entirely the RMI4 over SMBus module. And then we can not
probe for it, meaning you are stuck with the PS/2 crappy mode.

We are aware of this bug and we'll try to fix that. I think the test you
provides are valid (the patch works as expected), but a different bug
prevents rmi-smbus to fully initialize the touchpad :(

Could you try applying Lyude's patch: http://patchwork.ozlabs.org/patch/780865/
(on top of mine, of course).

In the dmesg, you should see a Synaptics TMXXXX device appearing after
trying to set up the SMBus companion.

Cheers,
Benjamin
