Here is a good one...

I wanted to see how well svgalib would cope with the state that the
console is left in after X exits.  I did an apt-cache search for svga
and instead of picking something boring like a dvi reader I installed
lsdoom.

Here is my test:

 - run X         - all good
 - exit X        - console is not restored
 - run lsdoom    - display changes, but is not set properly
 - kill lsdoom   - console is restored

Neat.  So I just have to see what svgalib does to return to console
mode... or we could bundle doom with the -amd driver. :)
