This is controlled by a hardware switch, so we should poll it in order
to pick up changes.  (There does not appear to be an interrupt or any
other notification mechanism).
    

With the exception of this one they all look fine - I'm moving house 
next week and won't have access to any Dell hardware for over a month, 
so if anyone else could confirm that these work that would be excellent.

  

Ok, thanks!

Here's something else I just noticed.  I was able to test this one myself.

Subject: [PATCH] dell-laptop: remove duplicate Kconfig entry under drivers/misc

This showed up as an unselectable option when using xconfig and
searching for "dell".  It must been overlooked when dell-laptop
was moved to drivers/platform/x86.
