I do have this bug also since some time (ok, some months, maybe over a year). Recently I stumble upon Bug#926906 and Bug#712584, both on Firefox accessing the grafix card and AppArmor blocking the access. Since all my crashed seemed to be preceded by a ratelimit and some audit denies (like the poster above stated) I reasoned, if the bugs are connected in some weird way, lets say AppArmor block firefox from accessing /dev/ati/card0 and the overflow on ratelimit crashes the system ? At least I now adapted my firefox apparmor profile and gave it access to /dev/ati/card0. The audit messages are gone and so is the ratelimit msg. I'll watch the situation and post back, if my crashes are gone.
For NVidia the bug was fixed with a new abstraction for apparmor.
