The following rules DTRT, though obviously it'd be nice if a more generic (but still safe) rule could be devised. SUBSYSTEM=="input", KERNEL=="event*", SUBSYSTEMS=="platform", KERNELS =="gpio-keys.6", PROGRAM="/bin/grep '^HP ProLiant m400 Server Cartridge$' /proc/device-tree/model", TAG+="power-switch" SUBSYSTEM=="input", KERNEL=="event*", SUBSYSTEMS=="platform", KERNELS=="gpio_keys.12", ATTRS{keys}=="116", PROGRAM="/bin/cat /proc/device-tree/model", RESULT=="HP ProLiant m800 Server Cartridge", TAG+="power-switch" You'll notice a couple of differences between the two. The m800 rule specifies a key attribute where the m400 rule does not. This is because the first uses a polled gpio via the gpio-keyboard-polled driver. This driver does not expose a "keys" attribute in sysfs. The m400 uses the gpio-keyboard driver, which does. You'll also notice the grep vs. cat/RESULT methods. Not sure if upstream has a preference. It might make sense to drop the model/pin matching of the m800 rule, and bind to any ATTR{keys}=="116" - this is defined as KEY_POWER in <linux/input.h>. Of course, that won't help the -polled variant.
