Nope. Here's the output from freshly booted machine without
loading forewire and just after starting X with DRI.

But I think dri works as glxgears produce something like 425 FPS. BTW:
-su-2.05b# pkg_info | grep dri
dri-4.3.0,1 OpenGL hardware acceleration drivers for XFree86
And dmesg of in this state is below my signature.
