True geek ports Ubuntu Linux to 8 bit CPU
-----------------------------------------

The guy takes an 8 bit CPU, writes an ARM CPU instruction emulator, adds SDRAM and SDCard, and then boots Ubuntu. Takes 6 hours to boot - but hey thats just a slow motion way of saying it can be done!! :-)
It is nothing to be scoffed at though. The little embedded CPUs are heading to 200MHz. Even under emulation, may still reach a couple of emulated MIPs in a year or less. Thats still powerful enough to boot Linux in minutes and make it good enough for security applications and weather applications for little more than $5 to get it going!
