Note from Daniel, who is looking into this bug.
-----
Quick recap: this problem happens because we don't have the wake-up from software suspend implemented in the pseries machine. In fact, at least last time I checked, only the x86 machines implement it.
I've send patches to the QEMU ML about 3 months ago to implement a new API (well, technically a change in an existing API) to detect whether the guest has this capability or not. The idea is to use it in Libvirt to prevent pm-suspend and similar commands to execute at all if the guest can't proper wake up. The patches were left behind along the way, and now people are working towards the RC releases of 2.12 (i.e just critical bug fixes).
I'll re-re-send that patches aiming for 2.13 and see if we can finally get them upstream.
