It seems to be randomly broken, every boot in a slightly different
way on my i945gme. Works quite well on my Q35. So add an option to
disable it till this is resolved.
Well, more testing seems to suggest that I've been hunting ghosts.
Or maybe not and it works now simply because it's a different day.
Anyway, leave this in for future testing.

gem_stress maps all buffers, so more only results in trashing (which
should be handled with an option).

ddx and mesa assume that this is issued after every blit command.
Breaking that invariant results in a dying gpu.

The busy bo has a fixed size (1024x256, 32bpp) whereas the scratch bo
may need to vary their size to exercise different features of fence
allocation.

And a few other things:
- inline checking when copying tiles with the cpu, fails _much_ faster.
- bo size seems to have a tremendous effect, put on the TODO.
