Hey! I don't know how much I can offer, but I'm in a similar boat--$250 for "travel expenses" after already being "[recommended] to the Dean of the Graduate School that you be admitted to our PhD program concentrating in _______ for Fall 2013" (which, as far as I know from this school, is a formality). In the same email the POI also said they were "pleased to inform you that you are being considered for a Departmental Assistantship Award, which covers tuition, stipend and health insurance." So, I think it's not a guarantee or anything, but it's certainly a good sign--you're obviously in, at least, and they want to make a good impression on you! I don't know how standard it is to offer travel funds to all admitted candidates, though, or if it bodes well for funding. I'd also be interested in hearing others' responses!
