>Description:
After fresh reboot and if current powerd state is adaptive:
# powerd -a adaptive -b adaptive -n adaptive
# primes 44


After some calculations terminal (vtty) display will lock.
But system is still completly usefull (except that nothing new is
displayed on monitor, even if Xorg is started)

It is probably also still present in 7.0 PRELEASE
>How-To-Repeat:
run this on fresh reboot

# powerd -a adaptive -b adaptive -n adaptive
# primes 44

but it is somehow not 100% reproducible with this (read: it doesnt
work all the time) happens with both ULE and 4BSD, but it seems that
with 4BSD is more reproducible (every time when I tested kernel with
4BSD it actually lock the display)
