compose doesn't work in console, br-dvorak

Binary package hint: xkeyboard-config

In installing the Hardy beta, I've configured my keyboard to use the new layout br-dvorak. It works fine in X, but in the console I can't type accentuated letters, i.e. ã, ó, ò, etc. The rest of the keymap is normal, and I can type the individual symbols, ~ ^.
I think the problem is with the hardy (or freedesktop) packaging, as I had that package (in console-setup) layout manually installed (from http://tecladobrasileiro.org/) in gutsy and it worked flawlessly.
