I just made the two obvious changes - expand the memory range on the ddr 
controller in mhs to 0x80000000 - 0x81ffffff, and modified the ERAM_SIZE 
in mbvanilla.h to 0x2000000, and it works like a charm (see transcript 
below).  The cache range should probably also be expanded, I'll tr that 
next.

Let me know if you want the bitstream or kernel image to try.

Cheers,

John
