just copy and paste the commands into the terminal, it shouldn't take too long, I'm not convinced there is actually an easier way. I really don't like the way Xandros does this.
The other option, is to install Ubuntu - I reckon we can get it working in there (and with surprising ease), though you will probably need an SD card todo this and it will take time to install Ubuntu. In fact, I think this is going to be the easier route.
