First of all, happy release to you all.
I have noticed that NVIDIA released two beta drivers which work with Intrepid’s X.org and I will make new packages available in the -proposed archives ASAP. In the meantime you might want to see why I recommend you to wait for these packages. Keep an eye this bug report so as to know when these packages are available for testing.
As regards Hardy, I need a plan to backport driver 177 from Intrepid without breaking dist-upgrades and/or the available drivers. I should also update the fglrx driver in my lrm-envy.
Stay tuned.
