[wplug] Hibernating Fedora Core 3

[Scott Husek]

This recipe worked for FC3 on my desktop (APM), which I then applied to my
wife's FC3 laptop (ACPI).  However, it completely disregards the ACPI
support in the kernel, so you might not be interested in this.  It's the
swsusp2 stuff from sourceforge.  It takes her laptop about 30 seconds to
go down, and the same to come up.  On the plus side, the only glitch she's
noticed thus far is that the USB card reader has "issues" sometimes.  I
told her to just reboot when that happens.  She liked the simplicity of
that, and I liked not having to troubleshoot it anymore.  Anyway, here's
my notes (typos and all) from when I installed it:

########################################################################
### swsusp2 (hibernate) install/config

cd myinitrd
gzip -dc < /boot/initrd-2.6.9-swsusp2.img | cpio -i

mounting root)
emacs init

#
# download and configure the hibernate script
cd /usr/local/src/swsusp2_stuff
wget http://download.berlios.de/softwaresuspend/hibernate-1.02-1.i386.rpm
rpm -Uvh hibernate-1.02-1.i386.rpm
emacs /etc/hibernate/hibernate.conf

If anyone wants, I can post the hibernate.conf file I'm using too.

Since this actually shuts the computer off, to resume you simply boot it
up.  It should detect the suspend image in the swap space and pickup where
you left off.

As much as I'd love to use ACPI for the laptop, it simply wasn't working
for me.  However, I've been quite happy with this setup, because my wife
has been quite happy with this setup.  ;)

Oh, if you use yum, don't forget to add this to yum.conf:
exclude=kernel*
