T210:
By default max power savings is enabled.
By changing `newpowersave=` to 0, it reverts to the old behavior of smaller power savings.
This was added to mitigate some strange DRAM chips, hanging from constant frequency change of a 800 MHz - 1600 MHz back and forth.
T210B01:
Defaults to a simple loop with no power savings. That's because of untrained ram.
