Simply use the patch I sent earlier and modify the svn revision number used for checkout. if it is done soon, the change will get enough testers.

I'm not sure I understand. Stage 1 is essential for stage 2 unless you want to switch compression infrastructure at the same time as compression algorithms (which would be horrible form a debug point of view).

Also, I'm going to be without any net access for 2 weeks starting in 24 hours, so waiting for stage 2 (lzma support in LinuxBIOS) will hold back current development. I'm not complaining if you clean up LinuxBIOS to make lzma support easier, but my current ETA for working lzma is 3 weeks from now.

Maybe, but since current LinuxBIOS svn already has switched to the new infrastructure, I think patching Config.lb is overkill right now.

Ron/Jordan, could you please test whether buildrom builds functional images with the attached patch? No changes in LinuxBIOS necessary as those are already upstream in the checked out version.
