We had someone working with VESA on exactly that and I thought that had 
shipped, but we found the same thing: the extension was never released 
and there's not currently a standard way to tag HMDs at the EDID-level, 
which is very unfortunate, as you'd want the lowest levels of the system 
to be aware of the HMD-ness of a display. You would never want to bring 
up a text console on one, or any sort of non-distorted content. I'll 
look into getting that effort back on track, but in the meantime it 
looks like an EDID blacklist somewhere might be our best bet.

Thanks,
