Comment # 15 on bug 1013647 from Max Staudt

No, I haven't. I can't find POINTINGSTICK_CONST_ACCEL in the kernel though, are
you sure the rule actually does something?

In any case, the problem is not the acceleration. That we can compensate for at
any level we like. The real problem is that we don't get minute movements at
all. And this is a problem of either:

 1. Bad hardware - which we can exclude if the problem does not occur on
Windows (can anybody test this?),
 2. The driver not handling this new hardware as it needs to - because it
hasn't been reverse engineered or implemented yet, or
 3. A bug in the driver, or a clash with a workaround for old (jittery?)
hardware.
