I tried Haiku Alpha1 (and some nightly builds as well) on a Sony UX490N, which used to be a Sony premium model (Core Solo cpu).
I works surprisingly well (boots and responds ok, wired lan works), but I have a problem.
It has a stick for navigating instead of the mouse (like on those ThinkPad laptops, the little red stick in the middle of the keyboard). It is also used to mouse left click, but it is so sensitive, that makes the entire thing unusable.
Is there a way to disable the click function and retaining the mouse movements?
