Well, this is just a tiny bit of the answer.  But I do happen to know 
that you can initiate a suspend with:

echo -n "mem" > /sys/power/state

When it wakes up, you will probably have a black screen.  This is 
expected, I think.  There's more that needs to be done for a working 
suspend.  But at least it may give you a clue if kernel support for 
suspend is available.
