"hibernate command from the KDE laptop module disappears"

Same here on FC6 kernel-2.6.22.1-32.fc6 for BOTH a Dell D620 AND a Toshiba 
Satellite A45-S120.

Hibernate worked on the previous kernel for both machines: 
kernel-2.6.20-1.2962.fc6

Hibernate is still unavailable with kernel-2.6.22.2-42.fc6

True as well with 2.6.22.4-65.fc7. It looks like it is not supported anymore!
But the nice thing is that suspend is instead working better.

I had some issue here klaptop don't show hibernate option anymore ! This hapens
after upgrade the kernels I don't recall the number for sure but 2.6.21 or 2.6.22  

Can you run the pm-hibernate command from the command line?

yeap I can and it works

What should I do to add it to the klaptop applet? 

I'm not a kde user I'm afraid - toggling the shift or control keys may work but
I'll re-assign this as it is not a kernel issue and no doubt the relevant
maintainer can help you out.

Cheers
Chris

You assigned it to the reporter.  :)

Sorry for the noise Chuck. All the bugs are starting to merge into one...

There's a reason that klaptop isn't installed in fedora by default.  :)
If you have issues with it, I'd recommend taking them to upstream kde @
bugs.kde.org.  When/if you do, please let us know, so that we can continue to
track the issue.

Otherwise, my only suggestion(s) would be to use kpowersaver (or
gnome-power-manager), that properly support dbus/pm-utils

I think this is the bug on upstream kde 
http://bugs.kde.org/show_bug.cgi?id=148928

even the report have a patch suggestion 

still happens on fedora 8 

This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'.

Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists.

Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs:
http://docs.fedoraproject.org/release-notes/

The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

should be fixed in kdeutils-3.5.9 (which includes upstream patch)
