Come on, thats a bit over the top isn't it?

Thats hardly a big / complex patch. Besides that they are all intertwined:

 > * Add the individual alarm files.
As requested

 > * Add the tempX_max sysfs atrributes.
Reading tempX_max from the chip is needed to reset the alarms, as the chip 
doesn't do this itself. Exporting the userspace once read is only logical.

This is the result of you arguing (and me agreeing) that leaving resetting the 
alarms to userspace is very bad.

 > * Add (disabled) auto fan speed control trip points.
Thats just to document my findings while searching for the undocumented 
tempX_max registers, this is 6 lines in total, thats not worth a separate patch 
at all.

 > * Use arrays to reference register addresses.
Which is needed to implement the resetting of the fan and temp alarms sanely 
and thus is an integral part of the individual alarm files patch.

In the Netherlands we have a word for exercises like this its called 
"werkverschaffing" translated "work-providing". Please review the patch as is, 
I've got much better things todo then splitting up this absolutely reasonable 
sized patch (or arguing about splitting it up).
