Greg still claims that qcserial could be used by rebooting from Windows,
right?  In that it would still be extremly borderline to me, but it's
settled now.  We also have various SCSI HBA drivers that can be used
just fine, but contain tons ot ioctls for management tools that aren't
available as open source (or even easily obtainable at all).  Personally
I don't think we should merge those unless we have userspace code
available freely, but it's a less urgent issue than merging drivers that
can't be used at all.  The DRM modules fall to me exactly into that
category for "specialised hardware drivers that only have closed
applications", and the answer to those should be a clear no.
