This page:

http://www.audiomulch.com/~rossb/code/lockfree

points to various implementations, including a link to the Yann Orlarey
LAD post you mentioned, and also to much information. One of the
implementations - "lock-free-lib" - is reported to be GPL'd and to cover
Alpha, Mips, ia64, x86, PPC and Sparc.
