My 2 cents:
I think we should leave the onus of fixing the userspace to work with
the sane kernel API with the entity trying to get their drivers into the
kernel. I think it's a better approach (as in, more likelihood of
getting device support) than saying, we will only allow fully open
sourced kernel drivers.
