Ubuntu 10.10 Black Screen after update and reinstalling NVidia Drivers

So I ran into the situation where I was getting a black screen when gdm should be starting up. I was not able to switch to a different terminal but was able to ssh into the machine. I found the following crash dump in dmesg:

After quite a bit of searching without any luck I tried to remember what I had done prior. This had actually happened previously and I ended up reinstalling Ubuntu to fix the problem. It was very disheartening when it happened again. I did recall that it had started happening shortly after I had setup this computer for dev work on Chromium. This problem had also started occurring after setting up to work on Chromium. One of the more invasive packages that I had installed is the gold replacement ld. Since part of the NVidia drivers involves building (I assume) kernel modules I thought this might be part of the problem - AND IT WAS! :-)

For now I just uninstalled binutils-gold, reinstalled the NVidia driver, and now X is starting up just fine.

Hope this helps someone else out there.
