As with any other embedded linux you want a console for kernel messages and ideally an interactive shell under the gui. Serial ports are still preferred for this (htc's phones have one with wierd voltages on the extusb headphone lines) - less advantageous possibilities are doing it over usb or even jtag extensions.
Ideally whatever bootloader runs before the kernel uses the same mechanism.
