In fact, you can. I built a 64 bits kernel on my amd64 workstation,
then installed that kernel (dpkg -i --force-architecture linux.deb)
on a 32 bits sarge installation. Ofcourse that box does have an
em64t capable processor.
It actually boots, and works fine.
You then have a 32 bits userland with a 64 bits kernel.
Advantages are that you can use 4 GB of memory per process
(no more 3/1 GB split), and you can better take advantage of
a lot of memory - no more low memory, high memory, PAE, etc.
Mike.
