I'm neither familiar with this stuff.

Probably, the ACPI event is still working. Another possibility is that your 
distribution uses the "kbd" driver which also handles the key events of the 
power button.
As I'm using Gentoo, I set up the xorg.conf manually and also the handlers for 
the power and sleep buttons. The sleep button *used* to create key events, but I 
didn't check that when trying the evdev configured xorg keyboard since my sleep 
button handler works with the ACPI event daemon.

I'll try playing around with the FDI files this evening.
