The thing is not only that it's useless.
It's just that this isn't even an achievement
Since there are virtual machine packages available for more or less all PPC distribution you can install one using only like one or two (very short) commands
In debian for PS3 for an example all you need to write to get this up and running is
"sudo apt-get update"
"sudo apt-get install vmware-player"
Then it's done, you just need to copy a win2k virtual image to your ps3 and there isn't anything else needed.
So basically.. this is nothing.
