This worries me a bit. I've never been able to have zaptel act in a 
stable manner when I enable this on an Intel(R) Celeron(R) CPU 1.70GHz. 
There's another celeron I've tried it on as well where I have not had 
success.

When enabling MMX I'd hear all sorts of weird sounds and distortions in 
conversations. Disabling MMX and all was fine. The last time I tried to 
use MMX was sometime around June/July with both the 1.2 and 1.4 releases.

I don't have any more information to provide other than it doesn't seem 
to work with Celerons, even though they say they support MMX.
