Live CD accessibility testing -- It just works! (mostly)

[Henrik Nilsen Omma]

After a few more bugfix commits (thanks Tollef!) the Live CD access 
stuff seems to mostly work.

Here is what works well:

 * High contrast mode starts up with the right theme

 * Magnification mode starts up

 * In screen reader mode gnopernicus comes up talking (yay!)

 * In minor-motor mode the sticky keys and mouse keys work well


Things that we might be able to improve for dapper:

 * The high contrast mode should also use large fonts

 * The position of the magnifier is sub-optimal (but this has proven 
tricky to track down)

 * GOK crashes from the live CD (but works on my desktop) -- I'll file a 
bug.


Things that look out of reach for dapper:

 * Ubiquity+gnopernicus does not produce speech output -- I'd love it of 
we found a magic solution to this, but I fear it will need some major 
work. Now that we know the issues we should be able to make a tidy 
solution for Edgy.

 * Many applications don't speak AT-SPI as well as they should, 
including Firefox and OpenOffice. I want to focus more on this in the 
next cycle. Perhaps we can form a team to test and report these problems 
upstream.
 

On the whole though, I've very pleased that we have taken some 
significant steps toward universal access in Dapper!
