No, they aren't -- Tabitha is correct. Developer keys have overriden
activation security since the first Bitfrost document:
http://wiki.laptop.org/go/OLPC_Bitfrost
The anti-theft system cannot be bypassed as long as #P_SF_CORE is
enabled (and disabling it requires a developer key). This, in
effect, means that a child is free to do any modification to her
machine's userspace (by disabling #P_SF_RUN without a developer
key), but cannot change the running kernel without requesting the
key. The key-issuing process incorporates a 14-day delay to allow
for a slow theft report to percolate up through the system, and is
only issued if the machine is not reported stolen at the end of
that period of time.
