If you haven't already, check out the Mashup Camp site for the latest details on Mashup Camp.  You can see an updated online flyer here: http://www.mashupcamp.com/dublinflyer.html.  If you're on jaiku, you can add dberlind as your contact to get updates and news and even Mashup Camp trivia.

Registration information can be found here: http://www.mashupcamp.com/mc2regform.html  There is also a section on the Mashup Camp site for submitting discussion topic proposals, lodging/travel information, and info on a few contests which will be taking place during the event.  The site was just redone as far as I can tell, so if it's been a while since you visited, be sure to check it out again.

Lastly the schedule is still a work in progress, but it is going here, so keep an eye on this page: http://wiki.mashupcamp.com/index.php/MashupU5schedule for all the latest session announcements and where to get your Speed Geek on.
