Unfortunately it's not possible at the moment, and I'd recommend against
running that configuration by default, since it will have a noticeable
impact on battery life.  We're working on it, and users of Intel
chipsets, at least, should have some relief come 7.2.

It can't, because it uses VBE.  Why would you want to get the EDID from
an external userspace tool?  It seems completely pointless, except as an
exercise to see if the second monitor was connected, which you can find
out from Xorg -probe anyway.
