I don't know much about how this particular code works, but I'd like to 
chime in and agree with Samuel that it's always better to try to merge 
in with what is commonly used instead of creating a separate custom version.

On that point, could someone explain to me the reasons why speakup is 
not in the default kernel? Is it very intrusive, or known to have 
serious stability bugs? Is it not maintained actively enough to be 
considered?
