You sure you want to port the kernel to ARM? It is not trivial... and

Is there any information about this port?
our other option is an Intel Atom processor, would you recommend this?


Check out http://www.debian.org/ports/arm/ for an existing port of the
kernel to an ARM processor. ARM processors run a completely different
instruction set to the ubiquitous Intel instruction set, in the same way
that PowerPC chips are entirely different. Performnig a port is a complex
undertaking and can easily run into thousands of man hours, so unless you
have the skill, knowledge and time I'd strongly recommend looking for an
existing port.

Intel Atom processors run the standard intel instruction set, so you can
just drop the kernel straight onto it. No porting needed. As such, unless
you really, REALLY need the reduced power consumption you'd get from using
an ARM chip, I'd strongly recommend you elect to go down the Atom route for
no reason other than you've just saved yourself a lot of work.
