This patch by kugel and me enables scrollwheel acceleration for the e200v2: fast wheel turning will cause lists to jump over items for fast scrolling.

Here is a new patch, it's compiling again (old patch didn't work since r20757), has a little faster acceleration and is more simple.

New one: a little more time between to wheelclicks to be recognized as repeat and a little comment change to make it more clear.

Seems to work well on my e260v2

During a missed read, you're not executing scrollwheel(), is that intended? I'd think you get more smooth acceleration if you executed it anyway (it'll give the same button, but increase repeat).

Yes, at the last try it was intended, but it worked not as good as the first try, so, here is a new patch which executes scrollwheel during a missed read (very similar to first patch).

This is basically the same patch than the one before, but with imo better acceleration behavior.
