I've also heard you can modify the grub config, but that requires rebooting, and if you're going to reboot, at least on my Lenovo T500, you can disable higher cstate via a BIOS setting (I think it's under config -> power -> cpu power management).
I rarely reboot my machine and instead using suspend/resume. It'd be much more handy if you could change the cstate at runtime.
