In many ways different Qualcomm generations are more different than a ST-ericsson and a Qualcomm of the same generation.
Of course the WP7-kernel must add support for ST-ericsson, but that is the same work as is needed for a new Qualcomm-SOC as well. And this is a pretty easy work for MS/Nokia since ST-ericsson will likely provide the basis for the drivers.
pretty much sums it up nicely
Basically most of these processors are based on ARM's architecture. In another word they're very similar
