[rescue] Sun Thumper info

[Patrick Finnegan]

I know from experience, that they are somewhat compatible one way but not
the other, from swapping cpu board and chassis.

The x4540 board works in an x4500 chassis, but the x4500 cpu board doesn't
work in an x4540 chassis, from what I remember.

Still there were some differences. YMMV.
