"I have Edgy, flashplugin-nonfree (as far as I can tell, this now installs Flash Player 9)"

You will only have version 9 if you use the edgy-backports repository. You can check the version of the package you currently have installed with 'apt-cache policy flashplugin-nonfree' and see what version your browser is currently running by visiting http://www.macromedia.com/software/flash/about/ .
