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 ?
