What is the OS using big endian?

It may not be that easy for supporting big endian.
XEN may need to access address space which belonging to guest OS,
So XEN need to take care of big endian.
Because Linux and Windows are using little endian, we don't take big endian 
into consideration from beginning.
There are many places we need to change for supporting big endian OS.

But, if you can describe your scenario in depth, Maybe we can increase the 
priority of supporting big endian OS.
