What's the end game for supporting these devices?

With the latest HEAD of Linus, first I get:
» Jun 10 12:19:17 cambrian kernel: psmouse serio1: synaptics: Your
touchpad (PNP: LEN0072 PNP0f13) says it can support a different bus.
If i2c-hid and hid-rmi are not used, you might want to try setting
psmouse.synaptics_intertouch to 1 and report this to
linux-input@vger.kernel.org.

Then if I patch drivers/input/mouse/synaptics.c and add "LEN0072" to
smbus_pnp_ids, this strange thing happens:

[    8.526635] psmouse serio1: synaptics: queried max coordinates: x

Notice how the trackpoint only appeared 100 seconds after boot (X was
already started and initially the trackpoint was not listed in xinput)

100 seconds is quire ridiculous. Could you please post your entire boot
log so we can understand what happened there.

Sorry for the delay, I was travelling and couldn't put more time into it …

There was nothing happening in-between (at least nothing in the logs).
Just to make this clear,
I'm running the lastest linus 4.12 tree, with this[1] one-liner patch
to add the X1 Carbon to smbus_pnp_ids.

after suspend and resume the trackpoint device does show up.
