I see you're looking at the CPU architecture field as well. There's a big gotcha related to that one; some ARMv6 CPUs report CPU architecture: 7.
Oops. To get it right, maybe one have to look up the "CPU part" field (and "CPU implementor"?) in a table.
But currently, it's used only to check for existence of armv6 instructions. I don't remember all the details, but one of the instructions seems to be uxtb, used in the aes code.
