And take their answers with a big grain of salt... There's nothing to be
ported back, really. UXA basically just removes the EXA code the intel
driver doesn't need. However, it could 'play nice with GEM and KMS' (i.e.
use buffer objects for pixmap storage) in pretty much the same way with EXA,
and the code that was removed would be inactive.
