PortaBase 2.0 beta 2 is now out. This one should be pretty stable, I'm just waiting on translations (and ideally PR1.2 so I can do some proper testing on the N900). The only reported issue that I haven't fixed is the "start screen flickering in fullscreen mode" problem mentioned above by silvermountain; I'm running the Diablo Qt libraries from extras and not seeing that, so it might be a problem with the ones in extras-devel.

All the links from the original post are still applicable. Let me know if you run into any problems, want to contribute, or have any other feedback.
