Note that in such setups (64 bit kernels and 32 bit userspace) *some*
software will not work correctly (perhaps it's limited to tightly
kernel-userspace integrated software).
One example is open-iscsi - you won't run 32 bit open-iscsi userspace on
a 64 bit kernel (at least it was impossible a couple of months ago).
