I'm observing the same, also with Arch Linux, and a ThinkPad x60:
# uname -a
Linux x60 3.1.1-1-ARCH #1 SMP PREEMPT Fri Nov 11 22:28:29 CET 2011
x86_64 Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz GenuineIntel GNU/Linux

The kernel config can be found here:
<http://projects.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/linux>.
