Description of problem:
Having the acpi_cpufreq module loaded vetos suspension (either to ram or to
disk) on certain systems and leaves a cryptic error message in the logs.

Version-Release number of selected component (if applicable):
cpuspeed-1.2.1-1.33
kernel-2.6.16-1.2133_FC5

How reproducible:
Reproducible every time.

Steps to Reproduce:
1. Boot the system.
2. Run pm-suspend .
  
Actual results:
Monitor blanks, disks power down but system powers back up straight away.

Expected results:
System to stay powered down until ACPI wake up event.

Additional info:
This is in the logs:

Using
modprobe -r acpi_cpufreq
beforehand lets the suspend happen successfully. acpi_cpufreq seems to be loaded
by the cpuspeed initscript. On a related note using
/sbin/chkconfig cpuspeed off
leaves cpuspeed turned on at runlevel 1.
