I'm having an issue in that my XFX 5850 only recognizes two screens while booting, but once booting it only sends signal to one monitor in Mountain Lion. In Lion this wasn't a problem

I'm also having another strange problem–– after installing mountain lion my 27 inch LED Cinema Display has a high pitched buzz when I wake the computer from sleep. However, when I restart the computer and start up the buzzing is completely eliminated. If I turn up the brightness on the display the buzzing increases. This effect did not happen under lion. Could there be any explanation for this?

Thanks!

PS... Just so you know, here's my hardware:
P8P67-M Pro with modified 3K BIOS
ATI Radeon 5850

Using ML GM or FR (final release) I'm assuming right? If so, is your 5850 loading the Uakari framebuffer?

Final release... I believe it is loading the Uakari framebuffer... I tried AtiConfig = Duckweed and it had the same effect though... but I'm not sure if it actually switched over to the right framebuffer?

Definitely using Uakari, here's the output from ioreg...

| | | | "@2,name" = <"ATY,Uakari">

Interestingly, the device ID reported here is 9968, where the actual device ID is 6899... could this have anything to do with it? I looked in the ATI5000Controller.kext and 6899 is definitely there.
