need help with suspend/waking up - pm-utils and acpid

OK I've decided that I need to start conserving my system and learning power management tips and tricks. I decided to start with suspending and hibernating. I was pleased to see that slackware 12.2 already includes the basic tools to do this with pm-untils and some other things that help with the process. Hibernating and resuming working just fine after configuring initrd and lilo.conf to resume from the swap partition. However, I seem to be missing something on the suspend to ram end. I appear to suspend to ram (as far as I can tell) with no problem. But I can't figure out how to wake the system up. are there other things I need to configure?

I have tried:
running pm-suspend by it self

editing /etc/acpi/ to make the power button run pm-suspend instead of shut down

ensured the pm-is-supported states that hibernate and suspend are supported (suspend-hybrid is not)

I have an ASUS M2N-SLI Delux motherboard )nForce 570 SLI MCP and one GeForce 7600 GT video card.

Can anybody point me to a good tutorial or experiences on their use of pm-suspend?

I almost wonder if something is turned off in my bios. Under the APM section wake on PCI was off and and saw that "power-on" keyboad and mouse were off. I enabled "power-on" for keyboard Ctrl-Esc. for ACPI, it was set to S1&S3 and enabled.

To get your machine to come out of a sleep state, you need to generate a wake-up event. This is typically generated by a hardware switch of some sort like the lid of a laptop, or the power button of a desktop machine. I would assume that you've tried pressing the power button and that doing so did not cause the system to wake up. What happens when you do this?

It seems that the problem would have to be one of two things:
1. The system isn't receiving the wake-up event,
2. The system is not suspending to ram correctly.
