fedora core 7 speakup modified and dectalk express support

[Adam Myrow]

The Dectalk drivers are not broken.  It's the probing for the serial port 
that is the problem.  In the case of Slackware 12.0, which uses 2.6.21.5, 
it is necessary to pass the serial port on the command line.  For example, 
"speakup_synth=dectlk speakup_ser=0" would be right for a Dectalk Express 
on /dev/ttyS0.  So, try this with Fedora and others using 2.6.21.X 
kernels.
