Created attachment 206037 [details] patch Implement logic for querying TBR and TBR frequency.
This builds for me on both amd64 and powerpc64.
It builds and packages fine for me with this patch applied on Mac mini G4 as well, please go ahead. It would be nice if you could also help to upstream this patch, thanks!
