Ok. I jumped on the Acer web site... The system is an APSK50 desktop. I
noticed the BIOS was from 2006 - the latest is R01-C1. I flashed that
using 'flashrom' which I found to be a lifesaver! I didn't have to get a
bootable DOS USB key etc! :D
From dmidecode:
BIOS Information
Vendor: Phoenix Technologies, LTD
Version: R01-C1
Release Date: 05/30/2007

Handle 0x0001, DMI type 1, 27 bytes
System Information

SKU Number:
Family:
The CPU is a socket 775 PentiumD 2.8Ghz.
I reset the BIOS to optimal defaults and fired it up. No real change :(

Did this before I rebooted. If I don't have DRIVER=p4-clockmod set in
/etc/sysconfig/cpuspeed, when I start it I get a prompt saying that its
started the ondemand passive cooling. I assume that this means zero
frequency scaling.
This is a curious thing - when doing this manually:
# /etc/init.d/cpuspeed start
Enabling p4-clockmod driver (passive cooling only): [ OK ]
So, unloading all modules and playing manually:
# modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq
(/lib/modules/2.6.35.10-74.fc14.i686/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko):
No such device
So we can't use acpi. drat. Load p4-clockmod:
# modprobe p4-clockmod
Then lets do some tests.
# pwd
/sys/devices/system/cpu/cpu0/cpufreq
# cat scaling_available_governors
userspace performance
# modprobe cpufreq-ondemand
# cat scaling_available_governors
ondemand userspace performance
# cat scaling_governor
performance
# echo ondemand > scaling_governor
# cat scaling_governor
performance
#
Interesting. Surely this should change to the ondemand governor?!

Going to look into this tomorrow. It's 3:33am now on 1/Jan/2011 - so
Happy New Year to all, and lets continue the awesome achievements shown
in Fedora :)
