the stratagus.zip worked for me, but as another user stated previously - not until I reinstalled wargus/stratagus after copying the data to /opt. Posting the procedure I followed in hopes it may help someone (not to clutter up the thread):

1) extract the stratagus.zip and copy that stratagus folder to your N900 (MyDocs)
2) xterm -> sudo gainroot
3) cp -r /home/user/MyDocs/stratagus /opt/
4) apt-get install --reinstall stratagus wargus
5) launch from the wargus shortcut
