Hmmm, I wonder if that's the free stuff without acceleration.
I would install firmware-linux-nonfree and check the logs to see that
the nonfree version is loading.
As mentioned elsewhere in this thread, are you running GNOME? This seems
to *need* acceleration features to run properly.
So you could attack the problem from the other side of the fence and
install a desktop that doesn't require acceleration e.g. xfce, lxde etc.
The choice is of course, yours.
