Damnit, I seem to be making one mistake after another, with no end to 
it. I'm truely sorry for wasting your time. 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
hw.acpi.cpu.cx_lowest: C1
sysctl: hw.acpi.cpu.cx_lowest: Invalid argument

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