27" Cinema Display Stays Black after cold boot or sleep

Question

I'm wondering if I'm alone here. After applying the LED firmware update, I am unable to get my Apple 27" LED or Dell u2711 to recognize the connection to my radeon 5870 after a wake from sleep or cold boot.
To get either monitor to work, I have to unplug both of them and plug in a DVI monitor to the radeon and cold boot with that, once the machine is booted, I am able to plugin the 2 minidisplay port connections and both monitors work fine.
Once I shutdown though, I have to do the same song and dance the next morning to get the displays to work.
The interesting part is once the radeon and display port monitors stop talking, The process I listed above is the only thing that works to get them "talking" again - I cannot even just plug a DVI monitor in when the machine is already on, or use the keyboard shortcut for detect displays.
My console logs report 2 different things.
1. The Dock is reporting breakpoints and errors to CGSGetDisplayBounds
2. THere are lots of errors relating to the AppleHDAController.cpp

Answer 1

For a lot of people the trick seems to be to reset the pram a certain amount of times. Yesterday I gave it one more try, reset it 5 times in a row and hoped it helped. Started the machine today after shutting it down the evening before, black screen. Resetting pram once again and everything works.
There's a threat (http://discussions.apple.com/thread.jspa?threadID=559906) running parallel to this one concerning the same problem. For the original poster of the question the solution was to run Disk Utility, check for problems and repair disk permissions.
Neither of this works for me.
