OK, so it's 32 bit on an amd64 you'll be doing

I would reconfigure the kernel and include things that you know ought to 
be there. Then move the disks over and see if it boots. Rinse, repeat, 
till it does.

Now the existing system should work with your new hardware and you can 
update your CFLAGS and 'emerge -e world' at your leisure.

That's the theory at least anyway :-)
