Sure you do, it is hidden inside of your x86_64 box.  ;)

Install the Linux-Vserver patch, set the option to emulate 32bit 
in your kernel config, build and boot kernel, install your choice
of 32bit distributions in an ARCH=x86 guest context.

I currently run Gentoo-32bit, Debian-32bit, Ubuntu-32bit on my
x86-64 box (all at the same time). It is a Core2Quad box.
Ah, yes, I also run the same threesum in 64bit also at the same time.

Bottom of the page: http://linux-vserver.org/Welcome_to_Linux-VServer.org
That project's idea of "Experimental" puts other project's idea of "Stable"
to shame.  ;)
