It's certainly possible to update the old machine, but the real question is, 
do you want to go through all that effort?

You will probably have to deal with multiple situations that follow this 
pattern:

some package version X needs to be upgraded to version x+2. But there's some 
other package that prevents you doing this immediately as there are blockers 
in place. So you upgrade the other package, then upgrade the first one to 
version X+1. Then do it all again to finally get the first package to version 
X+2

You also have python-2.4 in there which needs to go to 2.6. Ouch. I have 
horrible visions of running python-updater multiple times....

Gentoo shares its roots with FreeBSD but running Gentoo daily is always more 
involved than with FreeBSD, especially cases like this. You cannot just 
upgrade from eg Gentoo-5 to Gentoo-6 as these concepts do not exist.

It is so much easier to just backup your data files and re-install, then 
restore the data. It'll take a few hours, trying to upgrade might take days.

If you want to try, start with "emerge -avuND system", get that to complete 
and take it from there.
