Identifying Intel Atom Z500PT

[Robert Schwebel <r.schwebel@pengutronix.de>]

Does anyone have an idea how to properly identify an Atom Z500PT cpu?
The get_model_name() mechanics in arch/x86/kernel/cpu/common.c uses
cpuid() to find out about the brand id, which is "Genuine Intel(R) CPU"
with family 6 and model 28.

Below is the output of /proc/cpuinfo on that box:

root@phyCORE:~ cat /proc/cpuinfo | grep model | head -n 2
model           : 28
model name      : Genuine Intel(R) CPU        @ 1.10GHz
