Comment 8 for bug 1053269

I'm very surprised that neither of those fixes it! For each of those test kernels (patch1only and patch2only), please install and boot that kernel, capture the output from 'dmesg' , and post that here.

Also, please clarify exactly what happens... Are you saying that the black screen occurs post-grub, and then it *stays* black even after it has booted up all the way to the X login screen? Or are you saying that the screen goes black during the boot sequence but then lights itself up again at some point?
