Running Xterm on your PS3:
One suggestion I have is to rather than use the GUI on the PS3 (Because it's God awful slow), is to log into your PS3 remotely through SSH, and run xterm to forward the rendering to your remote machine.

To do this:

1. Log into the PS3 using the command ssh -X (PS3 IP), ex. ssh -X 255.255.255.255
2. Once logged in, simply run xterm.
