Good! 3d is not necessary for my needs (because Pandora OS will still be there for this), and for wifi if it don't work then I could put a wifi usb-key in an usb port.
If it's already planned to do this then Pandora is really open: very good.
But you just have said that some drivers are closed-source: do you know which ones?
I know this would not be easy (but if it was I would have no-interest to do it!).
But perhaps the best idea is to put a bootloader that allow us to choose between two options:
1°)Boot the Pandora OS
2°)Boot from SD slot
Then we could never touch the pandora OS, and still play with any...
I don't want to compile my Gentoo directly on the Pandora, I will compile it on a real pc and then I will put binaries on pandora.
It is possible to compile ARM binaries from a x86 Gentoo, wich is very great.
