I can confirm this on my system. After the update today, I can no longer use the guest-additions in the natty guest OS. Even after reinstalling the guest-additions, natty still wont recognize them and therefore there is no 3D, or any other feature that comes with the additions.

(Run these commands from your HOST machine)
apt-cache policy virtualbox-ose
