I decided to wait until some of these issues are resolved and the submitted patches found their way into Xfree86 CVS, because with all the posted patches this is a patch merging hell.
In one of the bugs Egbert Eich pointed to a wiki article that explains how to debug the XServer. I will continue reading it when I will enter the next round fighting with the via driver
