Jens, since the trapping will occur on the primary cpu, halting it, using the second core to execute the translation stage will not produce an increase in speed.

Unfortunately, no one seems to follow this point and we are still getting "wait and see" comments.
Or comments that we somehow are acting against the community's best interests by pointing this out.
The cure to the problem is easy, btw.
Once these first 1000 boards are sold, design a board that supports a PPC with a standard fpu.
The price increase would amount to about $10 in parts.
I'm willing to wait AND pay a slight premium (which in this case could be really slight).
