Yes, Mick, that was my first governor. I thought I'd try to see if it
would behave at top speed if I set it to "performance". No luck, though.
And I can easily change the governor. It swaps out to any of the
installed governors with aplomb, although I have to do this manually. I
can't change governors from gkrellm, for instance. If I change it
manually, the new governor shows up there, but it's read-only so to speak.

I don't know if the idle controller has anything to do with this but
here is what my idle controller looks like:

/sys/devices/system/cpu/cpuidle
08:43:14# ls -l;cat current_*
total 0
-r--r--r-- 1 root root 4096 Dec 30 08:43 current_driver
