Hi Luke, that's great news!  Thanks a bunch for helping make ubuntu
accessible, including the Live CD.

In past versions of gnome-mag and gnopernicus, there were problems with
horizontal magnification settings.  I believe that CVS HEAD of
gnopernicus and gnome-mag, together, have improved that situation.  But
I would not advocate that change without a bit of testing.

The gconf keys should be the right place to change the defaults - in the
schema default values, I think.

However, wouldn't it be better to provide fullscreen magnification
instead?  This gives a much better user experience.  It does require
that the 'dummy driver' for the XOrg server be installed, but it gives
access to the full screen.  I'm not sure what the implications for a
Live CD environment are, but if the Live CD is providing its own X
server, there are ways to restart it with the appropriate flags, if the
user indicates that s/he wants magnification.
