Should be.  In a E4000, I've had older IO boards running with 4883, and 
cpu boards 4882, 4312, 2976 in first slot, clock boards 2975 (prom 
updated) and 4346.  OBP was 3.2.29 (maybe 28 as well, don't remember), 
is now 3.2.30.

The E4000 with the 2975 doesn't run 250 cpus, only 167 and 335.  It 
boots ok then hangs when clock speed is boosted.
