Not sure if Is there any more useful documentation beside the datasheet of the ICH9 that i can refer to to read more about SPI chip programming?
Don't think there is a short cut. Just keep reading datasheet of the chipsets and flash chips you are interested in or run into trouble with. Keep reading the list (as you are already doing). You can often learn something at the IRC channel.
Maybe you will be familier with SPI programming some day then you can write something for the followers :-)
