OpenSolaris Upgrade to 107 failed

Today I upgraded to Build 107 of OpenSolaris. Everything was fine, but on the
reboot, the GUI didn't start.

There is a problem in the Xorg-Server regarding the intel chipset.

The logfile says:

Couldn't find PLL settings for mode!

Also removing my xorg.conf didn't help.

Perhaps I have to play around using VESA-Drivers until there is a fix.

Rebooting to Build 106 worked without problems.
