Linux "lowmem" size is 768MB for PowerPC. Loading at a higher address results
in a non-booting Linux kernel. So this warning makes sense and it's not
possible to load to 1GB.
Why do you want to change this? Does this cause you any troubles? Is Linux not
booting correctly? I don't see what you would "gain" by loading to 1GB.
Cheers,
Stefan
