Perhaps someone on this forum has done what you are asking and would be more help than me. 
I think it could be done, but you'd have to do some fiddling around. The concept is to make the iDVD theme part of your iDVD or iMovie created slideshow, so that it will play as part of the slideshow.
I don't know if this will work, but if I were experimenting I would try creating an iDVD project with just the theme in it, and then save that to your desktop as a disc image.  When you click on the icon of the disc image you have just created, you will see a Video_TS folder.  Open that and you will see a file containing the letters VOB.  Open that file. 
You need to convert that VOB file back to DV or Quicktime Movie which iMovie is designed to handle. For that you need  the free download MPEG Streamclip:
http://www.apple.com/downloads/macosx/video/mpegstreamclip.html
but you must also have the Apple mpeg2 plugin :
http://www.apple.com/quicktime/mpeg2/, which I believe costs about $20.
Open MPEG Streamclip and drag the VOB file to its window.  Go to the MPEG Streamclip file menu and click on Export to DV. 
After the export is done, you will have a DV file containing the iDVD theme.  I would try adding that clip as your first entry in your slide show, assuming that you are running iDVD7.  (You can't add a movie to a slideshow in iDVD6.)  When you play your slideshow hopefully it will play the DV clip containing the theme, then seamlessly followed by your slide show.   If it doesn't, try instead exporting the VOB file to a Quicktime Movie, and then try to add the Quicktime movie to your slideshow.
You might be able to do this easier if you created your slideshow in iMovie instead of iDVD.  You could make an iMovie with the iDVD theme clip as the lead clip, and then share your iMovie project to iDVD. 
Good luck with this.  As I said, perhaps someone else has an easier way to do this and will chime in.
