Even then, ARM user emulation seem to be the only one fully working.
I tried also Lenny on ARM, it had some minor problems, but was working.

I could add Lenny to the testing suite, it's not a problem.

My motivation for running a "foreign chroot" is basically "apt-get 
update; apt-get upgrade" for some filesystem images I use on embedded 
devices running Debian.

It's easier and faster to do so on a PC than on real hardware or in 
qemu-system emulation.


Running LTP might be a good idea for running on those architectures that 
pass the "debootstrap smoketest".
