If I understand your question right, I have looked into this. The functions which extract the raw temperature data use ACPI control structures which appear to be created automagically as part of the file open process. I have not been able to determine were they are created and so have not been able to call them directly (I am no expert on this by any means so I could be totally off base here). This would leave opening the /proc file inside the kernel as the only other option and I am not sure that making those kind of calls from kernel mode would be a good idea.
