Downgraded to Build 99 again

After I downloaded the Build 99 of OpenSolaris and installed it on the laptop
everything worked fine. Before continuing to configure, I tried another upgrade
with a fresh installed Build99 of OpenSolaris and it failed also to start the
Xserver ( also login on the command line was not possible ).
Starting in Single-User-Mode is possible.

So I reinstalled to Build 99 installed andconfigured and now I'm waiting for the
next version, perhaps this one will work.
