We did work on this for RHEL5, getting relocatable kernel support
working fine with S4. While doing it and since, I've been running
Suspend2 with the same patch.

Since that work, Vivek has done more modifications, but I can confirm
that the basic design is reliable with S4. Haven't tried S3, but can do.
Will report back shortly.

Regards,

Nigel
