Thanks, so the 449 is pin 129. Just wanted to double check.

Now, I just remembered that since i2c-hid is using the pin via irqchip
there was a bug where pinctrl-intel.c did not set the mode correctly.

This should be fixed with f5a26acf0162 ("pinctrl: intel: Initialize GPIO
properly when used through irqchip").

The fix was backported to v4.15.4 stable so could you try that and see
if it works any better?
