H Vanessa,

I spent some times in Uruguay working on accessibility topics and I 
proposed the usage of this software:

http://magnifier.sourceforge.net/

Later, Esteban Arias from Plan Ceibal (who I am CCing in this mail) 
modified the source code to obtain better results on the XO-1.

Plan Ceibal deployed the magnifying software on all the laptops in the 
country.

It has been quite a long time since I instaled it for the first time, 
but if you want to give it a try here are the terminal commands you need 
to execute on an XO-1  to get it installed:

wget 
http://downloads.sourceforge.net/project/magnifier/magnifier%20for%20Linux/3.3.2/magnifier-3.3.2-1.i586.rpm?use_mirror=switch
sudo rpm -i magnifier-3.3.2-1.i586.rpm
sudo yum install xbindkeys
touch .xbindkeysrc
echo "# Virtual Magnifying Glass" >> .xbindkeysrc
echo \"vmg\" >> .xbindkeysrc
echo "    m:0x0 + c:224" >> .xbindkeysrc
echo "xbindkeys" >> .xsession

After this sequence of commands, you will have to restart the XO. You 
will then be able to access the magnifying glass by pressing the F13 
key, the one to the right after the "volume up" key.

HTH
