Allrighty, some pm debugging showed that the hibernate/resume works as explained in the debugging manual
https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt

In short, pm_hibernate fails to write the suspend image correctly, but echo disk > /sys/power/state does. Not quite sure why, yet

Which hibernate method are you using to write the image? There are several choices. Perhaps you use method A to write it, but method B to resume. Method B finds no indication of a method B snapshot (because you have a method A snapshot), declares no snapshot, and fails to resume.

Interesting question. I used pm-hibernate and hibernate-script out of the box. Both fail. Using the echo disk >/sys/power/state works. I'll do some research into the different ways of writing the image and get back to you.

I know that sys-power/hibernate-script can be configured to use any of the major methods, depending on how you set its configuration file. I think pm-hibernate is also capable of using different methods, also depending on how it is configured. You need to look at the configuration files for the tool(s) you want to use to see which method they use. For sys-power/hibernate-script, the files are in /etc/hibernate. I do not know where pm-hibernate stores its configuration.

/usr/lib64/pm-utils/pm-functions is the file that seems to contain the meat and potatoes of the code. It does do a suspend via echo disk > /sys/power/state, but I've got to clone the function and add some logging to see why the steps differ.

You might want to see what it echoes to /sys/power/disk also. I've set it to "platform".
You may want to read to doc about the whole software suspend thing: less "/lib/modules/$(uname -r)/build/Documentation/power/swsusp.txt" for example.
I learned a lot and managed to get my suspend, hibernate and hybrid-sleep funtions all to work.
