The update was for the MDP to VGA connector. Not the dual-link DVI connector.
On an unrelated note, my MB's logic board had to be replaced due to a faulty ethernet adapter, since the USB and MDP are all part of the logic board, I am curious to see when I get my MB back (hopefully sometime next week), if there are any changes in the flickering and fuzzes issues.
If not, pissed that the Apple Store has had my computer for 7 days now, I will be harassing them endlessly until I get a working dual-link DVI adapter with my MB and 30" apple display..
