I strongly agree with this. As I understand it (I could be wrong) Strength is almost useless for a pure caster. Since I like dwarven mages, the Strength bonus reduces my enjoyment, as it seems to tell me that I am doing it "wrong". In a game emphazising freedom as much as Original Sin, this seems weird. Pyrofox' recommendation with changing it to Constitution is great, as Con benefits everyone and fits the dwarves perfectly.
Memory for elves is also great, as the memory acquisition through cannibalism feature gives elves a memory theme already.
Memory, Wits and Constitution are great racial bonus stats, as they can benefit everyone.
Of course, elves having something as wonderfully flavorful (in more ways than one) as corpse-eating makes everyone else's bonus boring in comparison (except the lizards' dragonbreath, I guess).
