Remove WPMU Dashboard reminder?

This really applies to all plugins I think, but form required me to select one.

It appears that having any plugin installed causes the admin pages for the plugin to show the notice to install the WPMU Dev Dashboard Plugin. All our code is under version control and there's no way we want an extension downloading anything- how do I remove this notice (it's really annoying).
Also: most of the answers in support/faq have links that don't work.
