I'm wondering if there's just some directory missing, or if this is a kernel thing, something missing in /sys or such... though I haven't recompiled any kernels since I last had this working. what seemed to break it was an 'emerge --depclean', after carefully selecting which deps to remove. I did a revdep-rebuild directly afterward, including an emerge -Dutv system and emerge -Dutv world the only other thing that I notice which broke was my ecomorph compositing with e17, though I doubt that's relevant.
