I meant downstream/upstream wrt *BSD ports, i.e.

upstream = the i915 linux driver
downstream = your port in *BSD

If you think of the Intel/customer relation, everything we do here in the
community is pretty much just best effort, done by developers and
maintainers because it's the right thing to do. I think intel as a company
doesn't care one bit about *BSD from a business perspective at all.
