Virtualbox may run faster if your CPU supports (and virtualbox is
using) virtualization extensions (vt-x on intel, amd-v on AMD).

I remember reading about some folks running a 64-bit kernel with a
32-bit userspace. This gave them the memory (etc) benefits, but
regular 32-bit compatibility (and limitations on the application
side).

I doubt any distros provide a 64-bit kernel for their 32-bit releases, though.
