how to read EDID/xrandr

[Ondrej Balaz]

Hi,
is it possible to get edid info (especialy vendor and product id) for 
each of xrandr screens through X11 api?

I'm creating utility to remember various devices connected to VGA output
of my laptop (their mode/resolution, position etc.). AFAIK there is no
better identificator than vendor+product_id pair. I can see both
informations for various devices in my Xorg.0.log but I don't know how
to "reaccess" them (if it's possible).

Thank you.
