1) I don't clearly remember the details, but I remember the fact that I had to
do a fair bunch of hacks because Qt on Linux doesn't give us precise
informations on the matter, this is the reason we don't have the inertial
scrolling on touchpad; if I remember correctly, unfortunately, everything goes
down the same pipe: mouse discrete scrolling, mouse free scroll, touchpad
scroll, etc.

And yes, I opened a Qt issue, and they told me to bugger off, you can see the
details on the original discussion

And yes, this is quite sad and is currently the bottleneck in getting all of
this working in a decent way, but I'm not sure if I have the energy to try and
patch upstream Qt 

2) By "you" I was meaning to the bug OP, not you David :P I'm sure you can
compile Okular 

3) It'be cool to have all the options in the Okular settings panel, I'm not
aware on a method to disable it
