AFAIK psim is a 603-ish CPU.  It might have an option to disable
the floating point to be more like the 40x CPUs but I am sure
it doesn't have 40x style peripheral simulators.

If they have, it might be worth it to make sure the verify the 
patches and if small enough submit them to gcc.  If they are larger,
we will have to verify FSF copyright paperwork as part of 
submitting them.  If we get that far, I can help with the paperwork
part.
