You could actually configure CC Mode only to do auto-newline on certain
types of brace.  For example, on one of these braces, type <CR> before it
to get it onto a line of its own.  Then do C-c C-s to get its "syntactic
context".  You'll get back something like "((bracelist-open 1523))".
Then make sure c-hanging-braces-alist looks something like this:

(setq c-hanging-braces-alist '((bracelist-open)
                               (bracelist-close)))

This will stop auto-newlines going in in these particular circumstances.
(Note:  auto-newlines are put on all braces apart from those in the list.
If you wanted an auto-newline only _after_ a statement-block `{' (say,
for Kernighan & Ritchie formatting) you'd have something like this:

   (setq c-hanging-braces-alist '((bracelist-open)
                                  (bracelist-close)
                                  (substatement-open after)))

).
