Well I must have come out of loop because it seams that there already
is some simulation software available -
http://www.linuxdevices.com/news/NS8620812400.html - not sure how much
of the CELL it actually simulates - the SPEs are after all not needed
to boot an OS, so it may just be the PPE which qemu also may have a
better shot at emulating.
