Are you referring to hibernation of laptops to disc? This does work on
some laptops (e.g. on some that use a seperate disc partition for it and
hibernate totally in the BIOS) but not on others that require OS
intervention.

There are several ways to do this for these special cases, including: 

1. Hook into each laptop vendor's implementation.

2. Implement it within NetBSD; a hibernate system call would save all
state to disc and set necessary flags so that on reboot the system is
resumed. (I believe there is a patch for Linux that does something
similar.)

AFAIK no-one is working on this.
