Nope, it failed also. It looks like the reject I got when I tried it on bare 2.6.26-rc5. There was
a patch in -mm3 on EDAC that modified multiple of the following code:

pdev->dev.bus_id references to a dev_name(&pdev->dev)

-mm3 is what dave used for his basis.

Since the -rc5-mm3 patch was broken (the kernel OOPs), I extracted the EDAC patch from that into a
simple patch I applied to -rc5 and then applied my patch set and run that kernel to verify it
worked. I just applied that same mini-mm patch to -rc8 and Dave's patch applied fine. Without that
mini-mm3 patch, it work apply
