BAT is already taking a while to run, and any modeset tests we add take
away more time. I think just a basic one should be good enough for BAT.
Imo BAT really should be just the "is this total crap?" test. We will
still run full igt (at least that's my goal) on any patch that goes in,
with the goal to run all the fast tests (less than 1 minute or so)
pre-merge. In this glorious future BAT will only decide whether more tests
should even be started.

Makes sense I'd say.
