If you've installed a complete 32-bit chroot installation, with everything
you want to run, on a different partition so you can select it with root=
on the kernel command line, and if it has been configured sufficiently to
boot independently (with the appropriate 32-bit kernel, modules, daemons,
and /etc files such as fstab fully configured), yes.

Basically, it's effectively a fully independent multi-boot system, where
the one boot option happens to be an x86 32-bit Gentoo that's also
configured as a 32-bit chroot to your 64-bit amd64 Gentoo.  The multi-boot
side of it could just as easily be MSWormOS or Fedora or Ubunto or FreeBSD
or whatever, but then of course it wouldn't work as a 32-bit chroot of
your Gentoo amd64 boot.

There's also an experimental and still-broken 32-bit userland profile, I
believe, which would be a 64-bit kernel with 32-bit everything else (don't
know how the toolchain would work, as a cross-compile or as a 64-bit
multilib, but all regular apps would be 32-bit anyway).  However, I'd not
suggest that except for the EXTREMELY adventurous, those already running
~arch and a whole host of masked packages, and thinking that's far too
stable and troublefree for their liking, as it will easily make
~arch+masked look like a walk in the park.

Dear Duncan, 
thanks.  This appears a mission.  I will have to reinst. Gentoo and
create a 32 partition.  Can you recommend a url of howto proceed thence.
Gavin.

How about the handbook? You installing Gentoo after all...

This is for installing on a machine.  How would I catenate this to a
chroot?

In fact the whole gentoo setup involves chroot.

just don't do the machine parts: partitions,mkfs,grub,fstab  and of course
the reboot ;)

Google "amd64 32bit chroot gentoo" and you find:

http://www.gentoo.org/proj/en/base/amd64/howtos/index.xml?part=1&chap=2

There is a great deal of overlap with the install docs -- especially if
you want to be able to boot to the chroot as a dual-boot and therefore
will need to build 32-bit kernel etc.  The install procedure for gentoo
is basically 1) boot from livecd or something - 2) create a chroot - 3)
turn the chroot into gentoo - 4) reboot to chroot and finalise.
Creating a basic 32-bit chroot under amd64 does most of steps 2) and 3).

Of course,

Thanks for highlighting my idiocy.
