If EDID information can not be had without blinking, then flicker free
boot and login is incompatible with multi-screen support that keys off
EDID support. Which of these features should not be implemented, in
your opinion?

If EDID information *can* be had without blinking, then
GetScreenResources is fine as is, and the randr and the drivers just
need to be fixed along the lines Dave suggested.
