Getting gl518sm sensors working

[David Baron <d_baron@012.net.il>]

I recently replaced by MB is an aopen (via chipset). After compiling the 
needed module (found by sensor-detect), here is what I get:
~$ sensors
gl518sm-i2c-0-2d
Adapter: SMBus Via Pro adapter at 5000
+5V:         +0.00 V  (min =  +4.68 V, max =  +5.18 V)
+3.3V:       +0.00 V  (min =  +3.74 V, max =  +4.14 V)
+12V:        +0.00 V  (min = +15.69 V, max = +17.36 V)
Vcore:       +2.03 V  (min =  +3.74 V, max =  +4.14 V)
fan1:       9230 RPM  (min = 1200 RPM, div = 8)
fan2:          0 RPM  (min = 1200 RPM, div = 8)
temp1:       +30.0°C  (high = +80.0°C, hyst = +75.0°C)
beep_enable:enabled

Only the core voltage registers. The chassis fan is not plugged  into the MB.

My old board had working plus and minus voltages, agp temperature, etc.

Anyone played with such a chipset and got more results?
