If your using yellowdog on an sdtv and the app is too big (can't hit apply etc) hold alt and use left-button on mouse to move the windows around. Second, there are third party repositories for the ps3 and ppc in general look up atrpms. there are a couple of others that escape me right now
, yellowdog can access 7 of the 8 spu's and an smp kernel is installed. i hope this answered a couple of gripes
