I'll at least give it a try.

Cedric, as a start, can you please provide the output of the following 
commands after the system is booted and with hp-wmi loaded:
$ grep . /sys/devices/platform/hp-wmi/*
$ ls -l /dev/input/*
$ cat /proc/bus/input/devices

Does an unload and reload of the module work correctly? What gets output 
in dmesg by that?

The strange thing is that the resume function does not do anything that's 
not also done in hp_wmi_input_setup(). The only thing I can think of is 
that we might need to test for wmi_has_guid(HPWMI_EVENT_GUID) because 
that model simply does not support input events.

Cheers,
FJP
