That's a myth, I've swapped out lots of mobos without re-installing XP.
Granted I always recomend a fresh install when you swap mobos, but it isn't absolutely necessary. I've went from a CUSL-2 (Tulatin Celeron 1.4@1.68) to a K7N2-L (Barton 2500, speeds change a lot still) to a NF7-s rev2 (same Barton 2500, speeds still change a lot but they're quicker now) without re-installing and without major problems.
