Ok, after looking at the device drivers more closely, I feel a little
silly for proposing the systemim patches for inclusion.

Are there any further issues with patches 5 and 6, the hvc_console
cleanup and rtas driver patches? It would surely be good to get them
in because they are required to run on the Mercury products that
are already shipping.

In this case, the definition of 'in' would probably be powerpc.git
and subsequently linux-2.6.17, or is there a different upstream
maintainer for console patches?

I think systemsim does have accurate models for a number of IDE and
network devices, but I would rather not have to use them because they will
run at a horribly slow speed, because they try to model the performance
of the devices relative to the CPU cycles.

For the cell simulator in particular, I think there is no model of the
spider-pic interrupt controller, which means that systemsim can not use
the models for the devices it uses on other platforms. Eric, is this still
correct?
