Indeed, here it a simple change in 'buffer-match-p'
that will support this case:

(add-to-list 'display-buffer-alist
             `((category . comint)
               (display-buffer-in-direction)
	       (direction . top)))

(display-buffer (get-buffer-create "blablabla")
		'(nil (category . comint)))
