I can confirm that this bug is still present in Hardy (development
release). I also have a PIII Dell Inspiron 8100 just like those above.
Here's some info:
:~$ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel

here's the cpu part of dmidecode:

finally,
:~$ cat /proc/ioports | grep CPU
0810-0815 : ACPI CPU throttle
Here is how I solved it.
:~$ sudo gedit /usr/share/powernowd/cpufreq-detect.sh
then scroll down a bit until you see this if statement:
if [ -f $IOPORTS ] && grep -q 'Intel .*ICH' $IOPORTS ; then
PIII_MODULE=speedstep-ich
else
PIII_MODULE=speedstep-smi
fi
and change it to:
if [ -f $IOPORTS ] && grep -q 'Intel .*ICH' $IOPORTS ; then
PIII_MODULE=speedstep-ich
else
PIII_MODULE=speedstep-ich
fi
save and reboot, presto.
