The 2.6.22 working branch for openmosix 2.6 is available under the simple open mosix project on source forge.
rsync or checkout from the branches/2.6.22
Inside the scripts directory is a script that will help you apply the patches to a vanilla 2.6.22 kernel from kernel.org. This 2.6.22 patch is based on the current 2.6.17 source with some modifications. The author of omuscd (
http://sourceforge.net/projects/omuscd/ ) was the major contributor that made this possible. I just provided some toasty hardware and a little moral support :)
i386 and x86_64 are the only supported platforms at this time.
