The bug report states it is in a review process... but to be sincere, I
don't mind the patch is accepted or not. The important thing (from my
POV, of course) is that it can be done and that's enough (again, for
me) :-)
I don't have the need of increasing the wheel scroll speed, but it would
be nice to have such option, of course. That's something users are
requesting a lot...

I have not read the patch code but how about by reducing (dividing/
substracting/fractioning operations) the events?

In the end it seems to be perfectly feasible:
1/ KDE (maybe because of Qt?) users already have such option
2/ There is a generic patch (evdev) for Xorg to implement it

I don't understand why you think it's something so hard to get.
Look, I have next to me my windows computer with a tree-button mouse (2
buttons+wheel) from the same brand and model I use with lenny and using
the default mouse driver (the one that comes with the OS).
Okay, so I have set there the mouse wheel scrolls down/up 3 lines at a
time (whatever-that-means-for-windows) and when I open a spreadsheet and
I scroll down I jump from raw 1 to raw 3. Fine.
Now I configure the wheel to jump "one page" at a time (whatever-that-
means-for-windows), go to the same spreadsheet and scrolling down takes
me from raw 1 to raw 64. That's a hughe gain for sheets with thousand of
records.
Yes, yes... windows is windows and linux is linux. I agree. But the
source of this problem shares the same nature (I can be wrong but I don't
think the mouse is treated so differently in both systems, it's a very
basic input device, nothing fancy) :-)
