No, I didn't mean to imply that in my response (
http://lists.infradead.org/pipermail/linux-arm-kernel/2011-December/078670.html).
It has worked in the past, but I haven't run it for a few kernel
versions now.

I was hoping that Phil would respond to the couple of questions I
had about differences, but he never did.

   arch/arm/configs/at91x40_defconfig

It would be really nice to get Phil's changes in a form that can be
applied to mainline.
