750 series with MEI protocol is a dog for
Multi-Processor system. If you are working for a
high-end products, change it NOW to G4+. 750 is G3.
GT64260 is not good enough for MP yet. Someting
related to 60xbus vs. MPX.
Anyway, right, for PPC MP system, the best way is:
64360 + G4
Also, try to read latest errota when doing the design.
