Hi Dmitry,
(Sorry for calling you Dimitry earlier :)

I am not exactly sure what the issue is that is described there.
As far as I know the touchpad does not report pressure (maybe the EeePC style touchpad does, but I do not have hands on experience with that). However the Xorg Synaptics driver requires pressure events to work. So I chose a default pressure value and the driver always toggles between no pressure and default pressure for no touch and touch respectively. This seems to work well for all my testers as I have not heard any complaints.
A related issue seems to be that the Ubuntu packaged version of the Xorg Synaptics driver appears to have a bug where adjusting MaxTapTime doesn't have any effect. In the absence of true pressure reporting this is the primary parameter to configure ones personal tapping preference for the Elantech touchpad. I believe the bug reporter in question wants to set this value to 0 to disable tapping altogether (although the TouchpadOff option would be better suited), but because of this bug cannot do so.
So all in all I am not quite sure that this is a problem with the Elantech driver per se.

Well, either is fine with me. Just getting it in the mainline kernel will give it a broader exposure and more testing I guess.
