The ACPI script that I use to suspend to RAM stopped functioning when
I upgraded to FC4 (worked fine in FC3). This time
(selinux-policy-targeted-1.23.18-17--forgot to mention that in my
previous message on screen blanking), the script does actually supend
and resume, but it appears not to update the hardware clock.
The suspend script is invoked on Fn-F4 and contains:
#!/bin/sh
# test script for measuring power drain during suspend-to-ram with ACPI
# from http://www.thinkwiki.org
# Changelog:
# added sync before S3
# changed sign of difference (positive drain)
# remove USB for external mouse before sleeping

When the script is invoked, the following messages are generated in
