Maybe you heard the recent news that the handcuffware in Sony PS3 has been
recently broken:

This is somewhat relevant to GRUB: It is now possible to port free operating
systems to the PS3, but they will need a bootloader. And GRUB already has
two key pieces:
- PowerPC support on other platforms
- Operation mode that starts GRUB as a userland process (grub-emu)
With the PS3 exploit, it is possible to get full access to physical memory. My
understanding of PowerPC architecture is very limited, but I believe this would
allow grub-emu to:
- Rise privilege level
- Disable interrupts
- Setup 1:1 MMU map
Thereby obtaining full control of the hardware.
I think it would be feasible to make a GSoC project for this, or at least the
beginning of it. Let me know if you'd like to be a mentor this summer.
