Currently working a progress-blocking issue with PPC64 TOC support within LLVMPipe as seen in http://llvm.org/bugs/show_bug.cgi?id=13313 and on-list as part of email thread http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-July/052224.html
Once through that blocking issue, should be able to get a better picture of how far off the LLVMPipe functionality is.
2012-10-08: Still work in progress. As a fallback Adam Jackson has proposed to use another software rendered that isn't relying on LLVMPipe and is currently working together with the #fedora-ppc team to make that work as a contigency plan for Fedora 18.
