They may be mainboard specific. The formulae rely on *suggested* resistor values, which the integrators may or may not follow. There definitely is a need for userspace conversion. Libsensors needs to be tunable by the user.
I don't know about the kernel conversion Jan is talking about (never coded a sensor driver myself), so I can't talk about this half, but I'm pretty sure you shouldn't even think of moving all conversions into kernel space.
Mark, Phil, maybe you could explain the reasons better than I would?
