Now that these drivers have been leaked, would it be possible to run Linux on old iPhones? From my understanding, the main reason it couldn't be done is because nobody had access to the driver source code, and now..
Disclaimer: I'm working with some other team members on the revival of the iEmu iPhone emulator.
It won't be if you taint what you are working on. Just looking at this will cause lots of legal problems down the road.
That will keep you safe.
I.E. someone looks at the leaked code and writes a specification, then posts/shares that spec, and another person or team uses the spec to write a compatible driver without having looked at the leaked source code.
Also iBoot is basically the "BIOS" of the phone. Just enough to get it up and running and then load iOS into memory and kick it off, so it wouldn't have drivers for things like the touch screen or accelerometer for example.
I'd disagree, this includes source code.
There are no interesting drivers there.
