Happy to do so as soon as someone tells me how. :) I've never heard of
VDSO before and have no idea how to convince ldd to actually provide the
required information.

Just to check, are you sure that your /usr/bin/scp is actually linked with
any other libraries? Mine isn't:
windlord:~> ldd /usr/bin/scp
linux-gate.so.1 => (0xb76e6000)
libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb757d000)
/lib/ld-linux.so.2 (0xb76e7000)
If the problem is just that the chroot script needs to ignore
linux-vdso.so.1 the way that it ignores linux-gate.so.1, that's a very
easy fix.
