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).

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.
