This is necessary because get_model() checks are case insensitive, and if the swapable check isn't, the swappable logic gets tied up in knots with models that are partially swapped out. Thanks to chris@cogdon.org for the report and extensive analysis, and Preston for his work on the draft patch. Backport of c04c03d from trunk.
