The following .config options in the kernel have worked around the issue
I think:

Testing with some of the OpenGL screensavers in xscreensaver seems to
show reasonable performance (well, good enough for my needs: this is a
work PC).

I'm not sure that's the proper solution though.  It at least confirms my
firmware binaries are good though, otherwise I'm certain it wouldn't be
working there either.
