In case anyone else hits this problem of using scratchbox on a Debian lenny 
64-bit system, I have got a workround.  I have a UML 32-bit kernel which 
seems to run on AMD64 (with latest lenny AMD64 kernel) and which supports 
building using scratchbox.

I have created a debian package for it (derived from the standard 
user-mode-linux package) which you can download from:

http://www.cobb.uk.net/NokiaIT/uml-maemo_2.6.25-1um-2maemo1_i386.deb

sources:

http://www.cobb.uk.net/NokiaIT/uml-maemo_2.6.25-1um-2maemo1.tar.gz

This installs on i386 but to install it on amd64 you have to force it:

dpkg --force-architecture -i uml-maemo_2.6.25-1um-2maemo1_i386.deb

To run the kernel, use /usr/bin/linux.uml.maemo.  Note that the kernel version 
number ends in -maemo-32 so that the modules (in /usr/lib/uml/modules) do not 
conflict with the standard user-mode-linux package.

Of course, to use this you have to create a disk image with the stuff you want 
installed, just as with any user-mode-linux (or qemu or vmware) emulator.
