Restoring lists and discussion groups

[Pigboy]

We currently have a process (outlined here

http://msd2d.com/newsletter_tip.aspx?section=sharepoint&id=6fbc9145-cc08-4a5b-a7d7-14b37e014672)

for recovering deleted documents from Sharepoint.

Is there a similar process for recovering list, calendar, and discussion group items that could be implemented, or if not, how can I recover a list object without having to completely restore the portal server.
