[rescue] Stack underflow on SS2 after FB swap

I disremember when Sun stopped updating OpenBoot for the sun4c. The 
overview on oracle's site implies that it was supported through version 
4.x, along with the sun4m and sun4u. That could be incorrect.

If it were true, it's *possible* that updating OpenBoot might be all 
that was necessary to make the TGX compatible. I also disremember what 
version of OpenBoot was installed on that SS2.

That said, good luck finding an update.
