According to /usr/src/linux/Documentation/cpufreq/user-guide.txt :

"These are files (/proc/sys/cpu/0/* ) for deprecated interfaces to cpufre=
q, which offer far
less functionality."

Many functionality are missing (have a look on user-guide for more detail=
s) but the userspace stuff works.
In fact you just forgot to activate it. To do so (you must be root):
$ echo -n "0%0%100%userspace" > /proc/cpufreq

and then you should have
$ cat /proc/sys/cpu/0/*
66000
66000
1000

Now you can echo the frequency you want in /proc/sys/cpu/0/speed !
Enjoy !!!
