You need special hdmi sdvo encoders - all the hdmi features are
optional and have been added in an update hdmi over sdvo spec. Note
that the sdvo hdmi code in i915 isn't too massively spec compliant
either since we fail to update the eld and a few related things.
Otherwise I'd have suggested to copypaste that ;-)
