On boot the iMac switches to the displayport input and shows the motherboard boot screen and grub but the screen goes dark when it gets into the graphical part of the boot and stays that way. I have also tried with the Fedora 16 alpha live disk and the same thing seems to happen.

If this is still an issue on kernels containing this patch, please reopen. If you reopen, please also attach a new dmesg (again with drm.debug=0xe), but please ensure that it contains everything from boot-up (the current one is cut off at the beginning).
