Thanks, Paul! I was just chatting with Kevin about this on IRC.  With
your patch and no_console_suspend, it works. :)

I needed no_console_suspend because it wouldn't work otherwise on
<3.3-rc1.

Now I tried a vanilla 3.3-rc5 without no_console_suspend and enabling
the UART wakeup and it works fine!

Thanks for your help, guys!
