Thanks. I guess flasher --help will give me the flag I need. I wonder if there is a Mac Intel version of flasher anywhere... (Nokia only offers Mac PPC) UPDATE: I flashed the nitdroid kernel with --set-rd-flags=serial-console (which flasher reported was set, numerically anyway), but when I use the Maemo command in the menu of NITdroid, the tablet just reboots back into NITdroid.
