[coreboot] ASUS P5B-vm mainboard

[Rene]

I want to add this board to coreboot.
why? It is probably a case of because its there.
I also understand that I'm not going to do this in a couple of days or 
weeks. ( I wonder if I will be able to get it done at all.
There is a lot of low-level stuff which is overwhelming)

Of this board
The cpu is ????? The socket LGA 775 i haven't seen it yet in the 
coreboot tree.
The super io Winbond W83627DHG (id=0xa0, rev=0x23) at 0x2e is 
supported.
The North-(G965)  and Southbridge(i82801H ICH8)  not. :-(

proc/cpuinfo

processor	: 1
vendor_id	: GenuineIntel
cpu family	: 6
model		: 15
model name	: Intel(R) Core(TM)2 CPU          6320  @ 1.86GHz
stepping	: 6
cpu MHz		: 1862.000
it is a LGA775 socket.

I thought of adding the mainboard/asus/p5b-vm/devicetree.cb first.

I use the mainboard/intel/d945clgf as a starting point.

Which brings me to a first question. What is de entry for this 
socket/cpu in devicetree.cb?
         device lapic_cluster 0 on
           chip cpu/intel/socket_441
                device lapic 0 on end
           end
         end



Is there a way to generate devicetree.cb from superio and lspci output 
and other info ?

secondly I'm a bit unsure how the keyboard pci info is derived my lspci 
looks like

the mainboard/intel/d945clgf/devicetree.cb has
                device pci 1f.0 on # LPC bridge
                    chip superio/winbond/w83627dhg          
#######should be for my board
                    device pnp 2e.0 off             # Floppy
                    end
                    device pnp 2e.3 off             # Parport
                    end

What I fail to understand is why these devices(floppy, keyboard, mouse, 
com and Parport) are not on the 1f.[0-9a-f] in d945clgf/devicetree.cb.
But that might be specific for that board. How can I find these for my 
board?
