I don't think that this has anything to do with(could be wrong
though).  

Mine seems to be doing the same thing.  Fan running pretty constantly
with not a lot going on.  

I went ahead and did the items that you suggested:

[sean at homebox ~]$ grep MHz /proc/cpuinfo
model name      : Intel(R) Pentium(R) M processor 1600MHz
cpu MHz         : 599.542

Also, my /etc/cpuspeed.conf:

VMAJOR=1
VMINOR=1

# uncomment this and set to the name of your CPUFreq module
#DRIVER="powernow-k7"

# Let background (nice) processes speed up the cpu
OPTS="$OPTS -n"

# Add your favorite options here
#OPTS="$OPTS -s 0 -i 10 -r"

# uncomment and modify this to check the state of the AC adapter
#OPTS="$OPTS -a /proc/acpi/ac_adapter/*/state"

# uncomment and modify this to check the system temperature
#OPTS="$OPTS -t /proc/acpi/thermal_zone/*/temperature 75"


Since I have no idea what I am doing either, should any of this be
modified?  I didn't see anything like this in FC3, so it must be some
kind of change in FC4.
