Google says to check /etc/acpi/events/... maybe it can do what you want.

IMHO this is not possible as this is a NON maskable interrupt, thus the processor MUST do the jump and there is no way a programmer (think OS) can hook into that.
... and so it SHOULD. Think the other way, you have a hung OS (locked) and you need to reset. IF this was maskable you could press that button, but nothing wopuld happen as the OS already is dead, requiring a power cycle.
If you want something to reboot the computer by pressing a button, i.e. no keyboard, use the power button as this is maskable. Catch this through inittab and shut down the computer nicely (I do this one a few machines).

Some of the Supermicro motherboards let you configure the reset button instead as another ACPI button, which you should be able to capture in the OS. This would be similar to the diagnostic button on many Dell servers which changes the blue led to amber (and seemingly little else.) Check your motherboard manual, there's either physical jumpers or an option in the BIOS.
