after rebuilding mesa with the patch applied and installing the resulting packages (specifically libgl1-mesa-dri:i386 as i traced the change code/function through the build process to that package and tf2 is i386 even on amd64, but also dependencies and associated packages) tf2 no longer prompts a gpu lockup (even after hours of game play, where it use to occur within 10 minutes).
