2.6.14 is a good starting point.  Older 2.6 kernels have support for  
MPC8540/MPC8560, I forget when we introduced it.

Extremely unlikely. While I think PSIM has some support for e500 I  
dont think it handles anything close enough to boot linux.

It should be. The kernel is build with -me500 being passed to the  
assembler. for the majority of code it doesn't matter.  it will  
mainly get proper decode of m{t,f}spr instructions and a few other  
things.
