I am 99% sure this functions correctly.  It's been a while but I think
it was tested early this year as part of the coreboot support bringup.

Bear in mind the usual caveats apply; if you're not using the open
source drivers for your card the manufacturer may have locked out
passthrough, etc.  nVidia is especially famous for this.
