I'd prefer to disable Power key completely, it's actually totally useless. I think there is something on ACPI/kernel level could be done to disable that key, but I haven't found it yet. When I need to sleep I just close macbook, when I rarely need to reboot I just press button “Reboot” in some package installation wizard (otherwise reboot could be done using apple menu). So this button make sense only in one case: laptop is not responding and you need to “hard-reset” it using loooong press, and that case is processed by low-level hardware, not high level ACPI driver.
