The Linux APM Daemon
Everything here is
my personal opinion.
I do not speak
for my employer.
The apmd package is a set of user-level programs to control the Advanced
Power Management system found in all modern laptop computers and most modern
apmd talks to the Linux kernel APM layer, which does all the hardware-dependent stuff; see Stephen Rothwell's page at Linuxcare Australia for information about the kernel layer.
The current version of apmd is version 3.0.2. It contains many changes since version 2.4, which was released back in 1996, and these have been tested long enough that I think it's stable.
If you run a 2.2.x kernel and want to experiment, Gabor Kuti (email@example.com) has made a kernel patch that allows you to "hibernate" any Linux system to disk, even if your computer's APM BIOS doesn't support it directly.

Let me know how it works for you!
