I have this working on mythbuntu 10.04 on some machines (C2Duo based) but not P4 based motherboards.  At a guess its a motherboard 
BIOS compatibility issue, the C2D's pretty much suspend out of the box.

My P4's seem to go through the motions of suspending, but then restart...!

Have you checked your BIOS settings?  WOL may be useful, but probably not a part of the problem here.
