Thanks to jostein@ on #openbsd, I now have a working touchpad. All it
took was disabling dwiic* in the kernel, and then both the touchpad
(wsmouse0) and touchscreen (wsmouse1) work.
I was also pointed by mlarkin to the intel_backlight
(https://github.com/jostein/intel_backlight_fbsd ) command which works
perfectly.
So with just one tweak and an extra userland command, the Dell XPS 9350
works 100% under OpenBSD:
- suspend works
- hibernation works
- sound works
- Xorg works, with brightness ajustments possible
- wifi works once you switch out the wifi chip
If you like 13" 3200x1800 screens in a 11.6" size laptop, I can only but
recommend this model.

I also tried the same fixes on the XPS 9370, and got the same succesful
result. However suspend & hibernation don't work for the time being.
Cheers,
Noth

It worked around 6.1 but no longer does, Xorg stopped working with 6.2
and only just started working with the snapshot I tried yesterday. I
hadn't updated in 1-2 months, so not sure when the fix went in for
inteldrm.

Hello again,
I updated to the latest snapshot and now Xorg works! But it has a
caveat, the pointer device detected is the touchscreen not the
touchpad.
It's assigned device wsmouse0 and ums1 doesn't seem to recognize the
touchpad anymore so no wsmouse1. I've tested this on the XPS 13
9350 and
my new 9370. Same results on both (do make sure you have the latest
firmware installed via fw_update).
Did the touchpad ever work or is this a recent regression?
