Since fafcf94e2b5732d1e13b440291c53115d2b172e9 introduced an edid size, it seems to have broken this path.

Although, I think there may be a problem with the mux switching since we shouldn't hit the hardcoded EDID unless DDC fails.
I've avoided having to do a MUX switch for DDC so far since I've no idea how to enumerate what the MUX is attached to properly.
Ah ok. That would explain the bugs where VGA/DVI ddc doesn't work you switch gfx.
