I have an intel 965GM and eselect opengl list only gives me xorg-x11. I dug around a fair bit last night and found [1] which brought to my attention that modesetting was not set up properly. Few kernel compilations later, and my modesetting module now loads fine. While it didn't make the issue go away for urxvt, my emacs is now usable again. Woohoo, I can do things again! There's always eshell and ansi-term which I can run in emacs so the crisis is at least somewhat averted while I figure out a solution. I thought I'd share the link for all other victims in hopes that it will help them. Sorry all for late reply but I was shifting my e-mail around and didn't notice the responses!
