I've used this site to keep up with IE6 / ~IE6+ oddities / workarounds:
http://work.arounds.org/
You could review what is a work around on IE6, and pat yourself on the back that you don't have to do it anymore ;) I think thats a 'treat' in itself.. time saved!
At least now you can focus 0 time on IE6, and more time on IE7, IE8 issues...
