"how can i chroot to gentoo amd64 from 32 bit Linux ??"

It sounds like he wants to chroot into an 64bit environment from an
existing 32bit environment. You can't execute 64bit code inside a
32bit chroot because the underlying kernel is still 32bit, and hence
can't understand the 64bit code.

Short of building a 64bit kernel (your suggestion) there's no way to
execute 64bit code from inside a 32bit system. And if he's going to go
to the trouble of building a 64bit kernel just for this chroot
(assuming his hardware supports 64bit which I am assuming it does), he
might as well migrate fully from the 32bit kernel he has and take full
advantage of a 64bit one.
