Out of curiosity: can you share what virtual machines are you thinking of?

I cannot spot anything in the dri2_fence code that would require an
actual non-SW driver.
On that grounds we're fine, but drisw.c simply cannot depend on dri2.c
- please flesh the relevant code to another file.

I'm leaning towards dri_flush.{c,h} although other suggestions are welcome.

Thanks
