This is a very simple guide that will teach you how to Install Ubuntu linux on the PS3 and to get more out of your powerful system .
Firstly, Download the Official PS3 Ubuntu Linux 7.04 Feisty Fawn ISO file and burn it to CD (It is recommended you use a download manager).
NOTE: You will have to manually setup the partitions during the setup, else the entire system will lock up during the setup wizard. When manually setting up the partitions, select 10GB for the main partition and setup the rest to be used for the swap area (i.e. filesystem type SWAP). You may well find that the Other OS partition (which appears as sda in the installer) has no partition table, in which case you will need to let the installer create one. This is fine and doesn't overwrite the real partition table on the PS3 disk (sda is a virtual disk created by the PS3 for Other OSes)
