I am currently using r1664 and have been experiencing this issue from prior to RC5. I am able to boot into lion without errors or bad display configs UNTIL I have a power outage or physically pull the power from the PSU. At this point I will receive the infamous error: "bad display config block signature (0xaaaaaaaa) ERROR: nVidia ROM Patching Failed!" The only solution for this is to leave the computer unplugged or to remove the GFX card for up to 12 hours. I am able to boot into Lion while receiving the Bad Display config however only one display will initialize and if I try anything that is using OpenGL or intensive graphics, the screen will go black (Framebuffer fails) and fill with artifacts, with no avail needing a reboot. I have been plagued by this since July 21st on the day I had Lion working and for the first time the GTX 580 working QE/CI etc. However due to the fact that I can resolve it by leaving it unplugged (pretty inconvenient at that) I haven't bothered to submit an issue. (I did however comment on issue 48). I will gladly test out potential fixes and help out any way I can to resolve this issue.
