You need to create a hibernation file on a suitable partition. Search the web 
for tphdisk or tphdisk.c, the source code contains the instructions. Be 
warned that hibernating is _slow_, you may be staring at a blank screen for 
two minutes without any indication that the system is still alive.
2.6 kernels (and patched earlier versions) have a feature called "software 
suspend" that may or may not be better than APM suspend. I have never tried 
it, however.
