Thanks everyone. All of a sudden I have had lots of response (you can tell 'cause my mailbox is full ) so I'll pick through the PMs tomorrow. I don't want to add too many folks to the beta list so I may pick and choose a bit; in general we'll be trying to (a) get a good variety of HW configurations and (b) try to pick people who are comfortable with doing some of the trial-and-error work that makes the beta testing useful. I'll probably need the weekend to get back to everyone -- thanks for all the PMs !
We have set up internal projects to track the qualification of each AGP board on the Linux driver; those should feed into the release note generation, so hopefully you should start seeing those messages soon.
