Don't hold your breath... Most of the measurements we do is because of real customer requirements to reduce their TCO or improve performance without increasing cost. And most of our customers do run commercially supported distributions and applications, so there's little options left. PS The wonderful thing about Linux on z/VM performance is that there often are multiple factors involved, and you cannot really predict the effect without measuring. As for running 32-bit applications in a 64-bit kernel, you would imagine the memory requirements to be also less because various objects are smaller in the 32-bit mode. But if there are also 64-bit binaries (that came with the distribution) you end up using both the 64-bit and the 32-bit glibc and other libraries. And that increases the footprint of your server. Depending on the actual numbers, the effect can go either way...
