It is possible remarkably often because systems often start off with a
"32 bit mode."

The AMD64 port of Debian/Linux includes a subsystem for this purpose,
including support for installing 32 bit libraries in a special area
for that purpose. It's good enough to get OpenOffice.org working,
which is no mean feat.

It's probably enough to let SBCL/CMUCL work. Managing them via the
package system might be a bit painful, because the "32 bit emulation"
part is a bit manual, but it's probably possible...
