It is going to be so easy to tell them apart.

Simply because onboard devices on Sparc are going to have
openfirmware, so there are going to be OF device properties and
whatnot we can probe for if necessary.

And the only difference the chips can have at this level is what kind
of PHY et al. are attached to the MAC.  Fundamentally the devices are
going to be the same.
