Yow! This is a Bad Thing! In my version:
/*
lmsysctl.h - Part of a Linux module for reading sensor data.
Copyright (c) 1997, 1998 Alexander Larsson <[EMAIL PROTECTED]>,
Frodo Looijaard <[EMAIL PROTECTED]> and Philip Edelbrock <[EMAIL PROTECTED]>
...(text deleted)
Integers are used instead of floats, and are scaled. The scaling factors
are enumerated below.

I turned up no floats or doubles with a grep. The version I have is
(from lmversion.h):
#define LM_DATE "19981001"
#define LM_VERSION "1.4.6"
so it looks like this one is probably safe.
