It's not that slow when you run it on a honking x86 box!

It won't be that hard to make it work for a 5206e/5272/528x/5249, at
least from the core perspective(just need to add the div/mod
instructions and the extra v2 insn for the 528x).  Adding in the v4
instructions shouldn't be too hard either.

I've looked at porting it over to GDB, and came to the same conclusion
about the scale of work required. It's probably easier to start over
using the GDB simulator framework.

Anyone game to help on that?

Do we really need all the peripherals?  Just the serial ports should do.
Besides, the UAE doesn't handle the GDB simulator framework either.
