A smart phone has 200MHz ARM CPU and 2GB flash card, which can run a full distribution of Linux. ARM also releases SMP and high speed processors for the Netbook market. Apparently, ARM and Intel architecture are competing on mobile computing market. More here
So I spent some day on trying to install Debian distribution for ARM. Before installation an embedded Linux on real hardware devices, it is better to try it with an emulator to avoid bricking the devices. I refer a web page written by a Debian maintainer to install the Debian on an emulator, QEMU.
