Dectalk USB mini-review

Hey Adam. Question on that Speakup interrupt thing you mentioned earlier. What kernel are you using, which Speakup CVS build? Reason I ask because I am experiencing similar problems on kernel 
2.6.6 with Speakup v-2.00 CVS: Tue Dec 28 15:10:59 EST 2004. Except I can never seem to interrupt speech at all, and I think somewhere the kernel hangs during the boot process. However, when 
there's no synthesizer plugged into the serial port i.e., my Dectalk, the kernel will boot just fine. All be it with a beep just before the login prompt comes up, however that's most likely 
another problem altogether.
