Here's one example: the Seagate DockStar is very similar to the
Marvell Sheevaplug (same Kirkwood SoC), but has a different amount of
SDRAM, different GPIOs, UART, etc.  Many of the other systems based on
this chip ("plug computers") would be similarly difficult to
distinguish at runtime.

Well saying that it's very similar, then listing differences like GPIOs that could easily be runtime-detectable, doesn't really pin down whether that's a problem or not.

What does "different amount of UART" mean when it is the "same Kirkwood SoC"?
