Why on earth would you want to do this?

Not easily.

The main problem is readability: a television has limited resolution,
meaning the text will be hard to read unless it is enlarged somewhat. In
addition, the MPEG-2 encoding tends to introduce distortion to sharp
edges, so you might have to make the text even larger to compensate, or
it will be too blurry.

The end result is that for more than a few lines of text, you would have
to split it up into multiple images, displayed like a photo slideshow on
the DVD.

You could do that, but JPEG will distort the text, and the JPEG to MPEG
conversion could introduce even more artifacts. Your best option would
be to start with an image format which uses lossless compression (e.g.
GIF or PNG) or no compression at all (e.g. TIFF), as long as iDVD can
import them.
