Unfortunately I have no clue (nor docs) how lvds->hdmi chains are supposed to work. For real hdmi support we'd need a few things at least: - some way to set up infoframes - some way to switch between single-link and dual-link lvds modes (for the higher resolutions) - some way to do hotplug detection (I guess we could use polling on the i2c pins as a fallback) All this needs a new hdmi_on_lvds encoder/connector with relevant code, plus a way to figure out whether we need this (either with a quirk table or by looking at some magic vbt value I'm not aware of). In short: Tons of work to make this work, and very unlikely that we'll get around to it. If you're bored though I could give you some ideas though on the #intel-gfx irc channel. I've reverted the quirk entry to fix the regression.
