First, you don't want APM (and it may not even exist in new laptops), 
you want its replacement, ACPI:-)

My laptop's down on the farm (and I'm not) so I can't check its 
settings. However, this stuff is configurable in KDE and probably Gnome. 
Take a look at the PM applets.

On my laptop, I have to press the power button. It's not different for 
XP Prof which is also installed.

btw My tosh has three buttons which can turn it on. Two of them are 
special-function keys that can be used at any time, and they stay 
latched until read. I could easily run a script during boot to perform 
some special action if either has been pressed - eg to choose between 
runlevels 3 and 5, to start home processes or work ones.

Conceivably, I could hack on grub and use them to choose between 
Windows, Linux and the menu based on which key I used to turn the 
machine on.
