There are way to hack the PS3 via Linux:
You can now dump your BlueRay images into ISO format using Linux on your Playstation 3. All that is required to drop the images onto your 60GB hard drive is to run the following command “dd if=/dev/cdrom of=/imagename.img”. So far there is no way to play your backed up games, but this is a good start.
Well if you get further into hacking the PS3, you can always create a dual boot system.
