I believe that FreeBSD code never does that. So, I reverted to $FreeBSD: src/sys/i386/i386/machdep.c,v 1.688.2.31 2012/06/13 15:25:52 jhb Exp $ and rebuilt the kernel. By making that one change my fan problem is fixed! No more 0x40 msgs, although I only have 1 core again due to my use of hint.apic.0.disabled="1" in /boot/loader.conf. So, the most recent changes done to machdep.c are the culprit! I also booted from a FreeBSD 9.0 CD and it has the same string of 0x40 error messages with its default configuration and an empty /boot/loader.conf file, so both the latest changes to BSD 8.3 as well as the BSD 9.0+ tree have got dealing with Intel Core Duo chips wrong. (My Pentium 4 and Intel Atom machines running RELENG_9 are fine and show no problems. It is just my old Toshiba Satellite U205 w/Core Duo that has these problems.) I booted from an OpenBSD 5.0 CD and it works just fine in every way. Maybe I'll just run OpenBSD 5 on the Toshiba and call it a day.
