PDA like hibernate mode

I would like to know if it is possible to emulate/implement a PDA "hibernate mode". I explain:

Entering hibernate mode:

1) store all needed information (context, periphreals states...) into SDRAM

2) put SDAM in self-refresh mode (will keep kernel and context during boad power-down)

3) stop the Linux kernel

4) shut-down the FPGA (and the board power)

Exiting hibernate mode (using an external wake-up logic to power-up the board)

1) booting FPGA from boot flash

2) restoring context and peripherals

3) restart kernel from where it exited (i.e from SDRAM), meaning : **NOT** rebooting the whole kernel from the program storage flash. I want a fast wake-up.

Is it possible ?

Can anybody help me ?
