creating hybrid-sleep on linux

Ok, my laptop can hibernate and suspend, what i want is to be able to copy the contents of my RAM to my HDD swap space but then have the machine enter s3 sleep, could someone help me write a script or give me pointers as to what i need to re-code to make this work?

Something like
dd if=/dev/mem of=/home/username/mem.bin bs=1024
acpiconf -s3
Use you own parameters for where you write to.

DD is also unforgiving.
look at man DD

unfortunately if i do this then it destroys my swapfs on that image making it impossible to resume from, i had another idea involving pm hooks, i thought that i may be able to place a hook at the right time just before shutdown that told it to suspend to ram


hdd, hibernate, ram, safe, sleep, swap, uswsusp
