I don't pretend to understand most of this fully.
On the board the PCI address space/PCI controller is apparently at 
0xfe240000
So I guess that when that byte is read it should read from 0xfe240000 + 
0x1400?
That doesn't happen and a read happens at 0x1400 and an oops results.
I don't know enough to point the finger really.

There are probably only 2 people using this board still too. So I doubt 
it really matters. :)

Cheers,

Daniel
