Low Power States

battatawada

Hi,

Looking to buy the UP2. Had a few questions regarding the supported low power states:
1) Is sleep state (S3 or S0i3) working on the board with android?
2) What are the other low power states supported by the hardware and are all of them functional in android too ?
3) I understand that for proper low power support, BIOS support is essential. Which states are supported by the current BIOS release ?
4) Is the BIOS source open, can it be re-built and flashed ?

Thanks,
