W'sup with this?  Top and 'cat /proc/cpuinfo' both say I have a Quad
Xeon box!  I've opened up one of these boxes, and there are only two
cpus!  Running Redhat 7.3, software RAID 1, stock smp kernel, no crazy
apps or anything on it at this point - we're just testing them out. 
Output from the commands are below, if anyone knows that I'm parsing
this wrong or why Redhat's reporting this, PLEASE let me know!
