Interestingly, I've run across a pile of M5s with RE-333's shipped w/256MB 
that don't have ECC (or at least the kernel doesnt detect it). I wasn't 
able to find any feedback from anyone who had seen Juniper shipping 
non-ECC, but I've now seen about 5 of these, so I'm really starting to 
wonder. :)
