Monitoring /dev/input/event0 for button presses

[Nigel Roberts <nigel@nobiscuit.com>]

Hi,

I'm running Debian 6.0.4 on an Iomega ix2-200 (Marvell Kirkwood) and I
can use /dev/input/event0 to detect button presses via the gpio-keys 
driver. 

So far I'm using a simple perl script to read from /dev/input/event0 and 
do things like shutdown the box when pressed for more than 5 seconds etc.
Is there a an existing system in Debian that does something like this
already, perhaps something like the kbrequest action in init? 

Regards,
Nigel
