Do I need to initialize the PAM (Programmable Attribute Map Register)?
it's a good idea. Some chipsets don't set to reasonable values and bad things can happen. At the same time I doubt this is your problem.
I think you're getting the idea of how to do this.
I haven't gone through the PAM register throughly, I need to read the specification Any tips on how to set the PAM register.
Also I have one question, along with this, I have some more registers like AGPCMD, AGPSTAT and etc.. to set the properties of the AGP port. Do I need to take care of these while configuring the DDR SDRAM.

Actually this register is used to do some memory mapping functionality.
it's really for DOS memory layout compatibility.
That means we are not worrying about the PAM during the RAM initialization. Is my assumption is correct?
yes but it doesn't hurt to set it.
