Hmm...  For evbppc there appears to be the following existing
combinations of cpu variants and interrupt variants:

oea + marvell
oea + pmppc
ibm4xx + ibm4xx

I'm wondering if a combination of modifying what module loads key off
for the evbppc port and "build same tree multiple times with different
settings" a'la netbsd32 would be a viable route to follow.


However, this does not deal with the "does it have altivec" variation
which one might stumble across within the oea series (e.g. g3 vs. g4),
perhaps that variation needs to be dealt with in a different manner?

"Saw." :)
