Ok, that's one of the prerequisities though, you only have to fix 
klaptopdaemon :-)

Compiling /usr/bin/klaptop_acpi_helper from svn should really fix that then, 

http://websvn.kde.org/trunk/KDE/kdeutils/klaptopdaemon/acpi_helper.cpp?rev=409203&view=log

Revision 403409 is the fix I was talking about. A brief look at the source 
should reveal which script is called, though. IIRC it was /usr/sbin/hibernate 
for suspend-to-disk.

If you're not planning going through this hassle, and you trust me enough I 
could just send you my hand-compiled binary, it does work here (for S4 & S3 
actually). Let me know in that case.

Hope this helps,
