The problem still persists in a -CURRENT as of February 14th (due to the recent threading related changes, all ports have been recompiled as well). It doesn't freeze but panics when I start X with DRI enabled. The monitor is in standby right after switching from the console, so I don't see anything while it's writing the core.
