HI.
Yes the omnibook_acpi module works very well, if it support
your laptop model... omnibook_acpi and omnibook modules don't
compete as there are designed for totally different ways to access
hardware which your laptop model support or does not.

Are you using a logoff splash screen solution ? or are you in front
of a plain text console when you see this "Power Down" message ?
A plain console might give you error messages that a splash screen
tool may hide.
Have you tried sys-rq combinations ? Alt+SysRq+b should instant reboot
your computer, if doesn't work you have a kernel panic.
(It is preferable to do a Alt+SysRq+u Alt+SysRq+s Alt+SysRq+b sequence
which will umount everything, sync your disk cache and finally reboot, that
way your filesystems may remain clean)
