I can confirm that, and I remember Pavel already did too.

Can you reproduce that? My notebook does not do anything on echoing 1 to
5 to /proc/acpi/sleep.

I assume it is not system related but has been introduced when
everything got split out to sleep.c though I am not sure about that (I
planned some debugging for tonight)

Not quite sure...I would start making sure that the kernel actually
notices that something has been echoed to sleep. There must be some
handling of sleep as a proc filesystem entry - maybe in sleep.c. Look
for it. I think starting there makes sense. If you find anything..let me
know...I would not have to do double work then.
