odd question?

There was only a very short period where most hardware speech 
synthesizers worked with standard linux kernels. For many years, you had 
to compile the kernel yourself to get speech at all regardless of 
whether you used hardware or software speech. Then for a brief period, 
support for the speakup screen reader was included in most stock kernels 
with support for hardware speech. Then somebody patched the kernel code 
deliberately to make hardware speech synths not work. This was done 
because the kernel developers disapproved of the way speakup talked to 
the hardware. I think the short period where stock kernels worked with 
hardware synths were numbered 2.3. That was several years ago.

Your best bet, if you want to use speakup with a hardware synth, is to 
compile the kernel after patching the code to re-enable hardware synths. 
I have directions for doing this on the web site of the International 
Association of Visually Impaired Technologists. 

Those instructions are kind of old and may not work on more recent 
kernels. Let me know if they need to be updated and I'll see if I can 
figure it out.
