I'd definately be reporting this one to Apple. It seems that of those of us with newer hardware that the graphics issues were fixed with 10.7.2 update.
You can report OSX issues with apple via http://www.apple.com/feedback/macosx.html
Don't forget to include your system information using apple=>about this mac so that they can look for a fix for your particualr model. And of course if you have any friends with this same issue and models get them to report it too.... the more people with the issue, the more likely it is to be looked as a a priority.
