We use MS Project Server for general resource and sprint planning:
It contains the sprint milestones, delivery/go live dates, and the resources
allocated to the teams including vacation information.
By doing so, we can also calculate sprint capacities, plan resources that are
not team memebers, show dependencies to other (non-agile) projects.

What about “board” support like StoryBoards, TaskBoards,…?

I’ve only tried Jira/Greenhopper for task visualization. MSProjects works better in the background, and is accepted in the non-agile departments.
