ver_linux output

This is an Acer Aspire One D250-1613 (Android+Windows) with Intel Atom N280 cpu
on a Intel 945GME chipset. I don't know about the motherboard. 

The problem: 

There are two ways to get CPU temperature on this laptop. (1) "acpi -V"
(/sys/class/thermal/thermal_zone0/temp) reports 26.8C fixed; this never
changes. (2) sensors use the coretemp module to report a temperature around
35-45C, however if one checks using hwmonitor in Windows, this temperature
range turns out to be the one for the hard disk. 

In sum, there is no way to get a CPU temperature reading on Linux. On Windows,
software like hwmonitor can correctly report CPU temperature, which is around
50-60C usually. 

I will attach ver_linux output, sensors output, acpidump, dmesg output that
might be relevant, lsmod, cpuinfo, and lspci -vvv. Thanks in advance.
