SoliRun HoneyComb LX2K(LX2160A) suspend to RAM feature

We are trying to enable some powermanagement features on QNX with honeycomb LX2K(LX2160A) platform. Some researches from our side shows this feature is not even supported on linux. We would like to confirm whether it is true or not. If S2R is supported, what kind of operation is used to trigger the resume opperation and is there any DOC or reference provided from SolidRun?

Thanks,
Yong
