How do you post to the wall on a facebook page (not profile)

I have a blog site written in php and it posts new blog posts to twitter and a blog ping automatically under the hood using simple http post requests passed using php curl.

I have a facebook page for the blog site and want the updates to be posted to the wall on the page, is there a simple way to do this?

What I really want is a url and set of params to parcel up as an http post request.

Note that this is to post to the wall on a new style page not a profile.
