New standalone version of the coretemp driver is available at
https://github.com/groeck/coretemp. Output now looks as follows.

SandyBridge, idle:

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +32.0°C  (high = +80.0°C, crit = +98.0°C)
Core 0:         +21.0°C  (high = +80.0°C, crit = +98.0°C)
Core 1:         +26.0°C  (high = +80.0°C, crit = +98.0°C)
Core 2:         +31.0°C  (high = +80.0°C, crit = +98.0°C)
Core 3:         +26.0°C  (high = +80.0°C, crit = +98.0°C)
Pkg power:       7.22 W  (max =  95.00 W, cap =  95.00 W)
Core power:    935.00 mW (max =  95.00 W)
Pkg energy:     43.81 kJ
Core energy:    48.28 kJ

SandyBridge, under load:

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +82.0°C  (high = +80.0°C, crit = +98.0°C)
Core 0:         +77.0°C  (high = +80.0°C, crit = +98.0°C)
Core 1:         +80.0°C  (high = +80.0°C, crit = +98.0°C)
Core 2:         +82.0°C  (high = +80.0°C, crit = +98.0°C)
Core 3:         +78.0°C  (high = +80.0°C, crit = +98.0°C)
Pkg power:      68.79 W  (max =  95.00 W, cap =  95.00 W)
Core power:     64.05 W  (max =  95.00 W)
Pkg energy:     54.10 kJ
Core energy:    56.86 kJ

IvyBridge, idle:

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +29.0°C  (high = +85.0°C, crit = +105.0°C)
Core 0:         +28.0°C  (high = +85.0°C, crit = +105.0°C)
Core 1:         +26.0°C  (high = +85.0°C, crit = +105.0°C)
Core 2:         +24.0°C  (high = +85.0°C, crit = +105.0°C)
Core 3:         +30.0°C  (high = +85.0°C, crit = +105.0°C)
Pkg power:       6.33 W  (max =  77.00 W, cap = 1000.00 W)
Core power:    545.00 mW  (max =  77.00 W, cap =   1.20 kW)
Pkg energy:     75.98 kJ
Core energy:     8.43 kJ

The large cap on IvyBridge is not a bug; torbostat reports the same values.

Key changes:
- report core power consumption
- dropped cap min and cap_max attributes
- Report cap only if enabled
- power_max now reports TDP

TODO before the code can be sent upstream:
- code review
- testing with suspend/resume and power consumption impact on laptops
