After I click on Jetpack's settings page, then click on the Configure button for "WordPress.com stats", the link for "Visit Site Stats to see your stats." is wrong
I had to modify module/stats.php stats_configuration_screen() to say:
printf( __( 'Visit Site Stats to see your stats.', 'jetpack' ), esc_url( add_query_arg( 'page', 'stats', admin_url( 'admin.php' ) ) ) ); ?></p>
to get the right link

I'm running WordPress 3.0.5 in a multisite setup.
