Hi Daniel,

This must definitely be because of the config options enabled recently
at my request: the rmi4_smbus module wasn't enabled until then. Perhaps
booting with 'psmouse.synaptics_intertouch=0' on the kernel command-line
can allow this to work normally for now?

Unfortunately I don't know enough about how this works to help much;
perhaps linux-input@vger.kernel.org can help you further.

Ben / Debian kernel maintainers: perhaps this module would be better off
disabled, or this functionality disabled by default. Given that this
hasn't had the expected result on my X270 anyway that doesn't seem like
a bad option to me.

HTH,
Chris
