Seconded. Better not wait 18 months this time.

This being said, I'm unfortunately _still_ experiencing the resume issue (unexpected fan
state) from time to time after resume. Really needs more investigation
to get that fixed somehow, eventually.

Also, the pre_suspend_kernelmode variable is superfluous indeed, as mentioned this
can be simplified.

Atom emergency shutdown works fine on my machine (blocked fan sometimes,
going tick-tick-tick on boot etc., nice way to test this BIOS feature ;),
thus given this extra protection I believe the driver can be committed as is
anyway, nevermind any remaining driver issues which _might_ perhaps
eventually still exist.
