I think the test suite is enough to fulfil the formal requirement of
having a working userspace. But still it would be nice to have at least
some simple accel functions working in the DDX. Maybe just to see on how
well the current design integrates into the DDX code.

So I wouldn't make a working DDX a hard requirement for merging G2D
code, but I suspect that if the kernel code goes into 3.10 instead of
3.9, we'll just naturally get to the point of working DDX accel by the
same time.
