I'm pretty sure Tiger still had a 32-bit kernel, even though it had
some 64-bit support. Snow Leopard has both a 32-bit and 64-bit kernel,
but in almost all macs it boots the 32-bit kernel by default. See here:

I'm on IRC as tallest.

Server on an xserve uses the 64 bit kernel by default iirc. I guess
the reasoning is to give consumer hardware vendors a chance to write
64 bit kexts. On the other hand, most applications from Apple
(Finder,
Terminal, Safari...) now support 64 bit, but obviously also only if
the hardware supports it (so on a core not-2 duo everything will be
32
bit as before).
Hmmm, that sounds weird, even my Tiger can do 64-bits stuff (the
kernel
that is). That was the whole idea: being able to address much more
memory. Anyway it obviously requires some scripting.
Either we default to 32-bits Prefix on Snow Leopard too, or we figure
out a way to see if we're running on a 64-bits capable machine so we
can
enable 64-bits on Snow Leopard where possible.
Thanks for the info!
