In the mobile space we have arm and it has plenty of registers doesn't it?

It does and AArch64 is not far away, given rate of change within the mobile/pad fad-driven world the new chips will start hitting market sooner rather than later.

I was thinking more of 32-bits Atom.

ARM Thumb wouldn't have many registers either, but I don't know whether you could (or could want to) build an ARM Thumb linux kernel.

Thumb and Thumb-2 have as many registers as ARM (32-bit). You can build a Thumb-2 kernel with CONFIG_THUMB2_KERNEL=y
