Dell D600 reporting wrong CPU speed on -current?

[Markus Bergkvist]

My Dell Latitude D600 seems to be reporting wrong cpu-speed. The dmesg
says
acpicpu0 at acpi0: C3, C3, C2, C1, FVS, 1600, 1600, 1400, 1200, 1000,
800, 600 M
Hz

which I believe to be correct. But this is what I get from sysctl
hw.cpuspeed=600
hw.setperf=100

Changing hw.setperf makes no difference
hw.cpuspeed=600
hw.setperf=50

Any ideas what might be wrong here?
