Problems with power button after latest acpi_button.c 1.18 change

Hello,
  after latest change to src/sys/dev/acpica/acpi_button.c, revision 1.18,
I have problems with power-button on my Asus L4000L notebook, now it works
just in some cases:
    System boot -> Press Power button -> Nothing happens = bad
However:
    System boot -> Press Fn+Zz -> System is sleeping -> Space -> System is
      running again -> Press Power button -> Systems goes down - ok

After reverting part of 1.18 change (see below), power button does work
again in all cases. Are you interested in some output from my notebook?
Do you know about notebooks, for which it helps and for which it breaks
something as for my Asus?
Thanks.
