Comment 9 for bug 1232877

I've made some (hopefully) interesting progress:

The firmware version seems to be 8, using the formula in the elantech_set_properties function, so I modified the file like this to force it to set hw_version to 4:

   }

Loaded the module:

And now getting some response from synclient:

I have no clue if everything is working as normal yet, though it appears the pointer is much snappier. I will try to configure scrolling, multitouch, etc and report back
