It works perfect now with OpenBSD 4.0-current on i386, though I had
two little problems:
After using setup_chroot.sh there were still two things missing in the
chroot:
/usr/lib/libc.so.40.3 is needed by /usr/libexec/sftp-server (see ldd
/usr/libexec/sftp-server)
/dev/null is also needed by /usr/libexec/sftp-server (make sure the
chroot partition isn't mounted nodev)
This post helped me with that:

After fixing this it works like a charm!
I cc'ed the author at that time but never got an response.
