That's super weird. Any idea why my strongbad reports 407 then? Is it
a firmware bug, or someone misprogrammed something? What can we do to
make the CPU recognized in strongbad?

...and just for extra info, I believe strongbad actually has the
slightly faster version of sc7180. It has a higher GPU/CPU speed. In
some places I've heard it called sc7185, but in other places I've
heard it called just sc7180 with a faster clock speed...
