Hi JJ, nice to see you still about here. Have been mostly absent (pretty vacant) for about a year myself.
From what I have read, OpenGL isn't supported under Linux on the PS3 anyway, so what's the point? An expensive word processor?
Additionally, the existing firmware only allows you two options - allocate 10GB to alternative OS with the rest for PS3OS, or allocate 10GB to PS3OS with the rest to alternative OS. Not the most useful options for configuring my 400GB hard drive for multi-booting.
Of course, 10GB for an Amiga partition would be quite nice, but...
