Thinkpad fan control

My Thinkpad T400s kept shutting down when it was busy doing CPU intensive work. It turns out that the fan did not speed up to a high enough level to cool down the CPU, and I’d find messages in /var/log/messages stating that the CPU was dangerously hot.

Load the thinkpad_acpi module with manual fan control enabled

The first thing I did was to make it possible to manually control the fan speed. In order for this to work, the thinkpad_acpi kernel module needs to be loaded with a specific parameter. This can be

/**
 * Currying Functions with Named Parameters.
 * @gunar, @drboolean, @dtipson 2016
 * 
 * Why does it return a thunk, though?
 *   Because in JS named arguments are opaque. There is no way of getting a function's named arguments list.
 *   e.g.
 *     const foo = function ({ a, b }) { }
 *     console.log(foo.arguments) // Throws. Ideally would return ['a', 'b'].
