My recollection is that, at least for the component I'm familiar with (audio/media), Android didn't become SMP safe until 3.0 and later versions. But that's just for media ... the problem you're seeing is before mediaserver process starts up, and I'm not familiar with early system bootup. AFAIK, SMP safety is not really about CPU speed, it's primarily about having the memory barriers at the right places.
