I've never overclocked and probably never will, but when one overclocks, is the power required/heat produced pretty much a linear function of the overclock amount?
No. It can even go thermonuclear if you push things high up a lot. That is why you see those liquid nitrogen stuff used in overclocking competitions/exhibitions/demos such as this.
The Model M is not for the faint of heart. You either like them or hate them.

This is mainly because of the increased core voltage which typically accompanies any serious overclocking attempt. Power consumed by a CMOS circuit is a fairly linear function of frequency at a given voltage; but power consumption (and heat dissipation) increases according to the square of the supply voltage.
