Sort-of. The Integrator boards aren't really big-endian, they're a little 
endian board with a CPU that can switch endianness.

There are many big-endian platforms.

I have very little confidence in linux actually working in big-endian mode on 
an integrator. I'd also expect some of the consequences to switching to 
big-endian mode to be non-obvious. Access to real hadware allows you to check 
whether you're hitting kernel bugs or qemu bugs.
