I now think my problem must be with the speakup_ltlk module. I compiled 
a kernel with the "return null" line commented out. So the speakup_ltlk 
module loads. And it even works sometimes. I'm not sure what I did to 
make it work for a while there. Mostly I just get silence from the 
hardware speech synth. Sometimes it speaks random characters.
