It had me confused for a while, because I'd convinced myself by code inspection that we only enabled iwMMXt if you manually asked for a pxa2xx CPU and not in the default 'max' CPU, and then I found this test case that we were running with the default CPU type and which was apparently passing :-) -- PMM
