The reason to change to 64bit is maybe I'll have 8 G= B instead of 4GB of memory. PAE is already enabled in kernel, so I have no = problem accessing memory above 3Gbyte. Is there any performance increase ca= n be expected if I spend my time on this migration/reinstall?

Thanks

Forget it, don't even try. You might succeed, but it will n= ot be worth the
effort. You will complete the following steps in about half the time:

1. Back up /etc and anything else you want to keep
2. Reinstall
3. Set CHOST to something suitable
4. emerge -e world
5. Restore stuff from step #1

It's an interesting exercise to try and do the migration, people who li= ke
puzzles enjoy it. If your goal is to have a 64 bit system using the route o= f
least pain, best to follow the path with lots of consensus around here - th= e
one above.
