Mac OS X is intrinsically 64 bits.

That is not true.
Only with Mac OSX 10.6 Server version Mac OSX itself was 64bit. Intel
versions had 64bit userspace, but not core in 64bit.

If you mean by that that there's no 64-bit kernel, that information should be obsolete. There is a 
64-bit kernel with 10.6 (n.b., normal MacOS, not only server), and some latest Macs boot it by 

Most recent Macs can boot it, if the user chooses so:

Bottom line, some Macs support the 64-bit kernel since about two years, and it's the default on 
some. Applications can still run in 32-bit mode. Some applications already run in 64-bit mode by 
default, I noticed - like Safari, Mail, Aperture.

And LO/OOo builds are built against 10.4 anyway, and that is 32bit on Intel.
