Symmetric multiprocessing is available, but it's often much less hassle to have a single CPU running at 200 MHz than to try games with multiple processors (which means more PCB real estate, more sockets, more of other things).
As far as SMP goes, it's actually not all that expensive. People in the linux-smp list have reported differences of as little as $50 for a uniprocessor vs. dual pentium system. Of course, every so often we'll get a message about a $30,000 system that can handle up to <drool>64 Pentium Pros</drool>!
Check out http://www.ssd.intel.com/tflop.html, where Intel is building a 9000 Pentium Pro (200 MHz) machine for Sandia. Yes, it runs Unix, and they've already delivered the first 64 processor node. When finished, it will have 600Gbyte RAM, 200Tbyte disk, and run at about 1.8 Tflops, and cover about 1600 square feet. Price? 46 M$, or about $5k/processor.
