Hm... I get the feeling that my box is ALMOST fast enough, so anything 
else getting shoved off onto another CPU could be enough.

That's true of my OTHER smp machine, but there isn't any Mach64 DRI yet.  
My current desktop is a PII 400 SMP, so it can play everything fine except 
for full-sized DivX (720x480 will "drop frames" during lots of motion).

I'd be happy to help test (or code) any SMP changes.

I'll keep an eye open.  Thanks!
