Been there, done that. A lot of times when I had a problem with the base
system (from 5.3-RELEASE uptil now) it turned out to be "pilot error".

Let's step back to where I
started; dev.cpu.0.cx_supported *does* exist:

# sysctl dev.cpu.0.cx_supported
dev.cpu.0.cx_supported: C1/0

And here's the problem; this is what I get when I fire up FreeBSD:

...
Starting ums0 moused:.
hw.acpi.cpu.cx_lowest: C1
sysctl: hw.acpi.cpu.cx_lowest: Invalid argument
Mounting NFS file systems:.
...

Taking the power_profile into account, I guess it comes something
similar to:

# sysctl hw.acpi.cpu.cx_lowest=C1/0

I'm not sure that this is what is being called. The '/0' is removed by awk:

$ sysctl -n hw.acpi.cpu.cx_supported
C1/0
$ sysctl -n hw.acpi.cpu.cx_supported |awk '{ print "C" split($0, a) }' - 2>/dev/null
C1

hw.acpi.cpu.cx_lowest: C1
sysctl: hw.acpi.cpu.cx_lowest: Invalid argument

Works fine here:

# sysctl hw.acpi.cpu.cx_lowest=C1/0
hw.acpi.cpu.cx_lowest: C1 -> C1

So, finally, the question now is why I get the "invalid argument".

The only thing I can think of is that you've defined
performance_cx_lowest or economy_cx_lowest to some bogus value in rc.conf.
