The DRI support for this card has been disabled in upstream git: "rc410: disable DRI by default due to it not working "
I guess the reason X worked with 2.6.20 is that the kernel didn't enable DRI for this card?
Workaround until this lands in Ubuntu: Add: Option "DRI" "off" to the Device section of /etc/X11/xorg.conf
