TuxOnIce has a long feature list, including the ability to cancel hibernating or resuming by pressing Escape, image compression to save time and space, a versatile plugin architecture, support for machines with Highmem, preemption and SMP.
The TuxOnIce website (this one) and mailing lists provide support for dealing with issues.
The primary author of TuxOnIce is Nigel Cunningham. A huge thanks must also go to Bernard Blackham, Florent Chabaud, Pavel Machek, Gabor Kuti and Michael Frank along with many others who have tested and contributed to the development of TuxOnIce.
You can get the source packages for the TuxOnIce kernel patch and tarballs for the userui and hibernate script from the downloads page.
Git trees can be found on GitHub.
TuxOnIce is included in all Sabayon flavours.

It's been quite a while since the TuxOnIce website was updated, but the patch hasn't fallen into disrepair. It has been quietly maintained at Nigel's account on Github, together with the Userui and Hibernate script packages.
Now, Nigel has begun work toward a 4.0 release. The major new functionality in this release will be support for incremental images. The idea is that you hibernate once, per normal. When that cycle resumes, the image is retained and the kernel starts tracking which pages of memory have changed since the image was written. Then, when you next wan
