I am running the smp kernel 2.6.15-27-386 which I got using uname -r so don't 
blame me if its not exactly that name, and my dual processor is working 

It bummed me out that Ubuntu bunted on detecting my processor, too.  

But since installing the smp kernels, everything seems to run just fine, and I 
see the 2 processors detected during boot using dmesg.
