I Also would love to know how to do this!
I’m really surprised that this has not been set up for pages like it is for post since you can have permalinks in the post.
I would like to add that someone showed me to this link
http://wordpress.org/support/topic/147118?replies=7
which has a link in it to a plugin called .html on pages
