Works fine here:

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

# sysctl hw.acpi.cpu.cx_lowest=C1/0
hw.acpi.cpu.cx_lowest: C1
sysctl: hw.acpi.cpu.cx_lowest: Invalid argument

# sysctl hw.acpi.cpu.cx_lowest=C1
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".

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.

Nope, I haven't touched anything like that. In fact this is a fairly clean install of FreeBSD. I haven't messed a lot around with anything. In /etc/defaults/rc.conf they're:

performance_cx_lowest="HIGH" # Online CPU idle state
economy_cx_lowest="HIGH" # Offline CPU idle state
