Yes that was intentional, since there are two ways to
scale the speed, namely moused and XFree. However the speed you
can see is already scaled down by an significant amount anyway.
Unfortunately the current sysmouse dosn't understand a witt
about absolute mouse coordinates as far as I understand the code...

Well for certain the down button does something in esp. it is posting
button 4 events. Watch out xev please - you should see it there.
Having a middle button was the reaon per se I did this hack in first place, so
this choice of numbering is likely here to stay.

Yes this kind of functionality is still not there, since it would involve
quite a lot of code, which I didn't find apriopriate to place in kernel
space.

moused -m 4=2 -m 5=4 should do it.
left is 1
up is 2
right is 3
down is 4

Yes. The next cut should define a custom SYNAPTICS mouse protocol and move
the whole logics out of the kernel to moused. There it should
be possible to implement all the extendid features one desires without
too much hassle. And without in esp. frequent reboots due to kernel crashing :-).

I'm glad this thingee works not just for my own hardware. Would
you dare to report the firmware version on your system.
