Good to see you're aware that the ATM7029 is actually a Cortex-A5 and not "A9 family" as the manufacturers claim. However, 1.5 GHz is also wrong, at least so far. The CPU is currently clocked at 1.2 GHz and since Actions lists the maximum speed as 1.3 GHz on their official website, it's unlikely that there'll be an official firmware running the ATM7029 at 1.5 GHz.
