I got an ilamp from someone and decided to set it up for my younger brother. Whatever osx was on it got really messed up to the point of not being usable. So I got another idea, and decided to install mintppc. I tried 11, but had a few problems that I couldn't figure out. I got another idea however, and am now hoping it works. What if I installed some other well working linux distro and put another lightweight window manager like jwm and a light desktop environment like rox (it seems to be the best really lightweight desktop environment, big gap after lxde) and maybe added any small missing things (not apt though, that has to be preinstalled, otherwise it shows that the os is missing other very useful utilities) to make a very lightweight, but still useful os? Thanks in advance for any help! 
P.S.Also, little less neccesary side question, could anyone help with the desktop being stuck in about 8 bits of color, maybe 16.
