I'm also hesitant to stick so many CPUs on something modeled after an e500v2-era mpc85xx. E.g. in the MPIC the upper bits of xIDR are used for EP/CIx. The newer MPIC used in p4080 and such move crit/mcheck routing into a separate register. There are similar constraints in guts (power management), and possibly elsewhere. -Scott
