Oh, yeah, the exact data format of the mmap'able area.

We need to store the character value and the attributes (bold, color etc).
We can settle on some common attributes, and leave it to the display driver to
deal with them, maybe the attributes even fit into a byte.  However, for the
character value, we should store the UCS-4, eg wide chars.

The basic questions here are:  Interleave the data (as we don't need 32 bits
for the attribute we face alignments issues) or keep it in seperate
"planes" (a bit evil when extending/truncating the scrollback buffer).
And what about endianess of the data?

Thanks,
Marcus
