Beta 4 and Modularized::Controllers

Seems that in beta 4 and master, a route defined in a namespace :foo,
or with controller: 'foo/bar', or with scope module: 'foo' always nets
one: 'wrong constant name Foo/barController'. Did the ways of setting
up routes to controllers in modules change? Or is it perhaps a problem
with b4 v. 1.9.2 (we were running these routes on 1.9.1 up to b4.)
