I am almost done with the 5219 guide so it will go live tomorrow. It has a LOT of information in it about tips, issue fixes etc… Here is a list of some of the things in it:

Installing Vista on SATA (Loading drivers IN SETUP)
WinRAR Massive Title Bar Bug Fix
DWM Lagginess Workaround
Fix for Random sound cut-outs
Sound Driver Reccomendations - This outlines what drivers work in vista for various popular sound devices
Hidden Goodies - Pointing out things that are there that MS failed to add shortcuts to.
MCE Issues/Tips - Outlines the MCE issue with LDDM and also a few helpful tips to get the most from the MCE experience.

More could be added by tomorrow, it depends how much stuff hits me between now and then :).
