I think we need a bigger hammer than this.

The problem is that when we disable acceleration (EIO returned from
execbuffer), the same thing happens. I think a fix for this should also
deal with that case. Probably something conditional on the
force_fallback member at dri2 time... (we can disallow dri2
connections, right?)

No patch from me yet, but I am thinking about it.
