According to the changelog in the url that driver is compatible with the ABI change introduced in 1.11 Would you mind to add that to the tree?
It's actually a typo. You can check with Nvidia themselves. It supported the beta ABI but not the final one. You'll have tons of graphics bugs and errors. I feel like I've made this same comment and closed out multiple times.. So who am I to stop people from having terrible graphics support, so its added to the tree.
When/if you run into a problem, please post a nvidia-bug-report.sh at http://www.nvnews.net/vbulletin/showthread.php?t=166025
