OK, I see.
So the problem is not explicitly related to ifupdown. With the same
config from above, this does not work:
$ sudo ifup eth1
ifup: unknown interface eth1
You expect that ifupdown matches an interface given as argument to the
lists of interfaces in auto, allow-hotplug, etc, even without defining
them, as long as they are known by the kernel.
