Can you please check the file permissions of /dev/dri/card* ?
libdrm in jaunty uses udev to create the device node, and I found /dev/dri/card0 now gets mode 660 (crw-rw----), instead of 666. If you get mode 660, please try to change the mode to 666 with sudo chmod 666 /dev/dri/card* and test performance again. For me, that gives a huge performance difference in sauerbraten.
(Kevin's xorg.conf sets dri mode to 666, but I am not sure if that still works now the device node is created via udev).
