Is this behavior (jumping pointer?) with the unpatched kernel?  I expected that
the patch may influence on this.

In anyway, if not done yet, please check the following with the patched kernel:
- Boot with the blacklist
- Try suspend / resume without re-binding
and let me know which problem is present.

FWIW, Fedora kernel "works" because the device is bound with i2c-hid, not
elantech.  Maybe they have some workaround in it or it's just a matter of
device binding order that casually worked.  But the suspend/resume problem
should remain with them unless any fix is applied.
