I'm using Mesa git HEAD. Desktop size is 1400x1050 but I also tried reducing it according to your hint - to no avail. I'm quite at a loss here. What possibilities are there to debug such issues? What could possibly cause a white screen? In fact, I believe compiz is actually running. I can see the mouse change if its over a terminal, and I can ctrl-c compiz to close it. DRI/GL is definitely up and running (glxgears, ppracer, GE). What I also found out with ppracer is that with FBTexPercent=0, OpenGL is considerably faster but some textures are broken. With FBTexPercent=50 the rendering is very jerky, but looks better.
