I think there is some confusion here: "coretemp" is a kernel module, and 
all applications reading it will probably use the lm_sensors libraries. 
(I don't think the hwmon module are related to ACPI)

$ modinfo coretemp
filename:       /lib/modules/2.6.25-ARCH/kernel/drivers/hwmon/coretemp.ko
license:        GPL
description:    Intel Core temperature monitor
author:         Rudolf Marek <r.marek@assembler.cz>
depends:
vermagic:       2.6.25-ARCH SMP preempt mod_unload

That said, I have two Core 2 CPUs (one mobile, one desktop) and the 
values coretemp reports have not changed compared to earlier kernel 
versions (around 60°C when idle on the mobile, much less on the desktop).

CONFIG_THERMAL=y?

The values I see from ACPI thermal are also the same as before (this is 
funny: they are always about 15°C cooler than the coretemp values).

So I don't see a regression here, maybe the reporter should try a 
vanilla kernel.
