CPU frequency control

Hi,
Some time in the last few days, X applications have started running very
slowly - apps that would have been redrawn instantly now take several
seconds (e.g. Gnumeric, Evo, Firefox). Playing DVDs in Xine still works
fine though.
I'm running a P4 2.5GHz machine with 1Gb of RAM, but when I look
at /proc/cpuinfo it shows the CPU frequency at more like 312MHz. I had
a look at the CPU frequency monitor applet in GNOME, and that also shows
the CPU frequency getting scaled back as soon as I stop doing anything
CPU intensive.
How can I stop the CPU frequency scaling, or at least limit it to
something a little more reasonable?
Kind regards,
Lyndon
