I found a document named "Understanding the Linux Virtual Memory Manager" quite helpful in this regard. Its a little dated at this point since the description in it covers how this works in the 2.4 kernel, so I don't know how applicable it is to 2.6, but the document is very well written. See: http://www.skynet.ie/~mel/projects/vm/ There's also a print version available at Amazon, et. al.
