The main question here is: is this a general requirement for these trackpoints,
or just one on your specific laptop? I don't use the trackpoint that much, but
I can tell even on the T440s I have it's not ideal - when it kicks in it's way
too fast.

no. the hwdb is not a configuration system, it's a system to store hw-specific
properties. the CONST_ACCEL property is there to roughly make pointing sticks
behave the same, similar to setting/adjusting the resolution on touchpads, etc.
The premise here is that libinput (or other input stacks) can use the hardware
with a known baseline and then go from there.
Again, the best solution here would be to write the patches for a separate
acceleration function and then go from there.

Note that the x230 patches I mentioned above only affect the touchpad, which is
pretty horrible. So I guess the same applies for you too - let's separate the
trackpoint accel out first, then we can start fine-tuning it.</pre>
