Found a couple more problems:
1) MI_DISPLAY_FLIP should take a '1' in the last byte to indicate
length on IVB
2) apprently only the BLT ring version of the command actually causes
interrupts to be generated
With this patch, modetest -v works on my test platform. Clearly it's in
need of more splitting though. The case statement should be split into
per-chipset flip command generation.

But it's not the neatest patch in the world ;-)
True :)
Using struct intel_ring_buffer *ring for all generation and switching
between blt/render on demand should be neater. Also we should be able
to do pageflips from either the render or blt ring on gen7, right? That
will be useful to avoid a synchronisation point.

I thought so, from reading the docs. But it doesn't seem to work from
the render ring...
