err 'yes' in that both the 060 and PPC can be active at once...indeed when a
PPC program is running, it needs the 68k so that iut can do OS stuff!
however, big swapping within the code between the 68k and the PPC will
incurr and penalty..known as 'context switching' which will slow your code
down as data structures get xfered
depends on how well your data is handled and how much you can keep in CPU
cache etc
