xScale and SID

Hallo SID-Developers,

I am going to develop for an Intel Xscale PXA255. The board will be equiped
with
Flash, Ethernet  and perhaps a CAN - Interface.
I am searching for some simulator and SID looks very interesting to me on
the first view.
But it seems as if there is no simulation available for Xscale
architectures. I
can't estimate how much work it will take to simulate such a hardware -
configuration.

May someone give me a hint about the amount and level of work to do?
Will it be more like a lot of configuration or will it include the
development of new SID-Components?

Thanks a lot - Malte
