Debian is perhaps a useful source here, since we have more architectures than most (any?) other distributions. It seems we currently only build the llvmpipe driver on i386 and x86-64 (including non-Linux kernels on those architectures, though). I'm sure the Debian Mesa maintainers would appreciate successful test reports for other platforms: a comment in the packaging indicates that they're only limiting llvmpipe to x86 because nobody has confirmed that it works elsewhere. I can confirm that under kvm virtualization on a modern laptop (Lenovo X220, using spice to display graphics in virt-manager), GNOME 3.6 uses fallback mode by default, but when forced to try Shell mode (gnome.fallback=0 on kernel command line), performance is fine (~ 15 fps). On the other hand, the Gallium swrast driver (not llvmpipe) on the same setup is not really usable (~ 1 fps). Shell performance is not our only problem with modern GNOME and non-llvmpipe software rendering: there have been reports that applications using Clutter (e.g. Empathy with libchamplain) just don't start.
