Hm, I guess the one in your workstation is a wierd variant.  Advancing the
product ID is a common tactic for showing different silicon & packaging
revisions, rather than bumping the PCI revision byte.  That particular rev
may be more prone to use chains due to memory requirements or whatever. I
guess the poweredge variants don't exercise that particular feature. :)
