The problem is known.  For whatever reason the manufacturer has decided to not
provide any direct way to access the display's EDID and we need to ask the
SBIOS to retrieve it for us.

Work to correct this is being done at
https://bugzilla.redhat.com/show_bug.cgi?id=536923.  Once fixes have been
confirmed, the patches will get upstreamed.

This should be fixed now.
Patrick, can you confirm this?
