[Openchrome-users] Direct Rendering VT8378 KM400

[Cinolt]

After updating to 9-CURRENT I was able to get Xorg to report (II) CHROME(0):
direct rendering enabled.

The problem is now whenever I try to open anything OpenGL-related everything
just stops responding, forcing me to reboot manually. I have no idea where
the problem is, or how to begin searching how to solve it.
