The frame parameters should each be elements at the same level as
"jabber-chat", rather than in their own enclosing list, as you've got it.
Also, it's better to use (add-to-list ...) rather than setq in this
context, because setq will clobber anything that's already there.

Put those together, and I think you get something like this:

(add-to-list 'special-display-regexps 
      '("jabber-chat" (top . 10) (height . 5) (left . 200)))
