speakup with ubuntu

[Jude DaShiell]

The ubuntu boot: prompt to be useful would need a single beep as it 
appeared on the screen and a short double beep when it left the screen. 
This way totally blind users with some useable hearing would be able to 
gauge when to do the keyboard commands to get ubuntu talking.  For the 
existing boot prompt, first is it possible to choose two accessibility 
options and what number would be usd to disable mouse input?  I need to 
get a rather large track ball to replace the mouse since that mouse ends 
up getting knocked around the desk and when hooked up gets me into no end 
of trouble with software.
