I did, but the problem got worse. With the following:
performance_cx_lowest="C2" # Online CPU idle state
economy_cx_lowest="C2" # Offline CPU idle state
X would begin to start up, but it would stay with a black screen and
never complete. Changing all 4 settings (cpu_freq and cx) to NONE
allowed it to start up again.
If I change it to C2 after I'm running my window manager the temp
drops after 10 minutes or so and the fan speed goes down as well.

/etc/rc.sysctl:
debug.debugger_on_panic=0
net.inet6.ip6.use_tempaddr=1
net.inet6.ip6.prefer_tempaddr=1
kern.module_path=/boot/kernel;/boot/modules;/usr/local/modules
/boot/loader.conf:
hw.pci.do_power_nodriver=3
umass_load="yes"
linux_load="YES"
nvidia_load="yes"
vboxdrv_load="yes"
if_wpi_load="yes"

egrep 'est|ichss|smist|p4tcc' /var/run/dmesg.boot
est0: <Enhanced SpeedStep Frequency Control> on cpu0
p4tcc0: <CPU Frequency Thermal Control> on cpu0
est1: <Enhanced SpeedStep Frequency Control> on cpu1
p4tcc1: <CPU Frequency Thermal Control> on cpu1

I haven't done anything special with the acpi stuff. The only thing
that looks relevant from dmesg is: acpi_tz0: <Thermal Zone> on acpi0
> Which nvidia driver?
The latest.

I can do the former easily enough, I assume to enable them I set
debug.acpi.disabled=0 in loader.conf?
