I tried the patch.  I compared experiences with or without the patch on
following setup.

  (setq mouse-wheel-scroll-amount '(1 ((shift) . 5) ((control))))
  (setq mouse-wheel-progressive-speed nil)

The scrolling experience is with more feel of acceleration.  I think
this is good.

I also compared with or without the patch on following setup.

  (setq mouse-wheel-scroll-amount '(5 ((shift) . 1) ((control))))
  (setq mouse-wheel-progressive-speed t)

Both are still too fast.

I think your patch handles two issues.  One improves response of
touchpad and other changes default values.  I think two issues should be
separated out.
