[ltp] middle mouse button and trackpoint scrolling: combining the two in xorg.conf

[Andrey Kislyuk]

"EmulateWheel" in xorg.conf enables scrolling with the trackpoint when 
the middle button is depressed. However, I haven't been able to make the 
middle button down+up event work as a middle button keypress when the 
mouse is not moving. I know there are "EmulateWheelButton" and 
"EmulateWheelButtonTimeout" options, but they don't work for me.

So, any accounts of getting it working in Xorg 6.8, and how does your 
xorg.conf look in that case? Does it work in Xorg 7, and what's the 
syntax there?
