Hm, thats strange. I've got a VIA-EPIA-EK8000EG with a W83697HG as well and 
didn't have any wrong readings with fan_input ( kernel).

By the way: I noticed that you are using the w83627hf_wdt in your 
kernel-config. Did you already test the watchdog? On my board the w83627hf_wdt 
loads correctly but does not work. I'm using the w83697_wdt instead.
