I have given up on appending VGA ROM with coreboot image. Instead I use the serial port for all the debug messages and then Geode LX frame buffer driver takes over immediately after loading the kernel.

Yes currently I am using the serial port and it works well.
 
Thanks for the clarification on the blob address. I am still wondering why I am coreboot is not able to see the VSA. The only other suspicsion I have is with the VGA ROM thats because the size was 32K and atleast for some other boards I read that it should be 36K and the last 4K of the VGA ROM cannot be retrived using "dd".
 
I tried searching for tools to decompress and extract the VGA ROM but the links seem to be broken...

I would recommend using the serial port for this.

--8<-- src/cpu/amd/model_lx/vsmsetup.c, do_vsmbios()
       rom = ((unsigned long)0) - (ROM_SIZE + 36 * 1024);
-->8--

As Marc confirmed it's hardcoded to the beginning of the defined rom
size, but not hardcoded to an address. Sorry for the confusion.
