I got around to installing Yellow Dog 6.1 using a DVD of the full distro. The installation went OK, and the installer fired up in graphical mode. However it proceeded to create the swap partition almost immediately because of low-memory concerns.
When it completed YDL was quite zippy – a much, much better experience than I got from FC12. I even had audio.
I may actually use this – it depends if I can get particular media players running on it.
