I have Srge running on many Dell servers including th 2850.  All dual 
processor machines with hyperthreading enabled that are running a SMP kernel 
show up in /proc/cpuinfo as 4 individual processors.  The fact that you see 2 
tells me you are most likely using a SMP kernel.  I would check my packing 
slip to ensure that the order included 2 processors.  Would not be the first 
time I have seen servers ordered differently because of changes to Dell's web 
site.  Other than that, I would open the machine up and look.
