No, it's not a bug in the kernel acpi code.  What can it do?  You have a 
button that's used to do two things - sleep and wakeup.  All it tells the 
kernel is that it has been pressed.

The same problem occurs with LID events.  Most, if not all, LIDs seem to send 
a counter of the number of times they've been pressed, so you could just test 
for even/odd - but you don't know whether the lid was open or closed when the 
system booted.

Anyway, for any such event you put both the deactivation and the reactivation 
code in the same script:

# deactivate code here
echo 4 > /proc/acpi/sleep
# good idea to sleep for a moment to let things wake up properly
sleep 1 
# activate code here

- because the script is still running when the machine comes out of
