NB: I have a 64bit environment running Arch32, with a core Arch64 
installed in another partition mounted as /mnt/arch64

I tried this:
mount --bind /dev /mnt/arch64/dev
mount --bind /dev/pts /mnt/arch64/dev/pts
mount --bind /dev/shm /mnt/arch64/dev/shm
mount -t proc none /mnt/arch64/proc
mount -t sysfs none /mnt/arch64/sys
linux64 chroot /mnt/arch64

but the latter does not work: I get
"chroot: cannot run command `/bin/bash': Exec format error"

Any idea? Or is it really impossible to do this as Mateusz was saying?

Thanks
