So what kind of laptop is this? You could post what CPU is built into it
or post the outputs of "cat /proc/cpuinfo" or "lspci", so maybe someone
may be able to tell you what you may try.
As I said in my original post, it's an old Compaq Armada M700. The output from
lspci was also in my original post, but here it is again, with an extra level
of verbosity:

changes to occur. Unfortunatly it has a really high latency when it
does frequency changes. So high in fact, that using ondemand with
it can introduce a really large performance hit, so it's explicitly
prevented from being enabled.
(There's probably a message in dmesg telling you this when you try).
Yes, there is. However, it seems that none of the cpu freq drivers are
suitable for my laptop. Never mind, I use it plugged into the mains most
of the time anyway.
