The kernels I have tried it with are 2.6.15-1-686 and 2.6.15-ck3 and
2.6.15 vanilla, and this happens with all of those.
When I try to enable the ondemand or the conservative governors it
gives an error message:

# pwd
/sys/devices/system/cpu/cpu0/cpufreq
# cat scaling_available_governors
userspace conservative ondemand performance
# echo performance > scaling_governor
# echo userspace > scaling_governor
# echo ondemand > scaling_governor
bash: echo: write error: invalid argument
# echo conservative > scaling_governor
bash: echo: write error: invalid argument
# cat scaling_governor
userspace

Here is some info about my system, tell me if you need more:
IBM Thinkpad R40 Laptop
Debian Sid updated yesterday
Pentium 4 2ghz

# lsmod | grep cpu
cpufreq_userspace 4216 1
cpufreq_conservative 6692 0
cpufreq_ondemand 5820 0
# lsmod | grep speed
speedstep_ich 4844 0
speedstep_lib 3972 1 speedstep_ich
freq_table 4164 1 speedstep_ich

Using powernowd with the userspace governor works fine.
