I've got my 2.6.6 kernel with acpi in it. I can use either
echo 1 > /proc/acpi/sleep
echo -n "standby" > /proc/power/state
and the laptop will go into standby mode. I can also do the other modes availble. However, I my laptop will not "wake up". When I press the power button to recover, the lights come back on and my wireless nic lights back up. The screen even turns back on, but its all black. Any ideas.

Check ACPI4Linux's website for info on the types of sleep states defined under the acpi spec. To determine what sleep states your notebook supports run cat /proc/acpi/sleep. As for actually getting stuff to wake up, note that linux's ACPI support, especially for S3, is sort of buggy atm. Look in the kernel sources Documentation/power/tricks.txt for some troubleshooting tips and take it from there.
