kernel. The sgi guys needed a kdump kernel with 1G of ram to dump their all of the memory on one of their crazy large machines and so investigated this. Basically they found that a kdump kernel loaded anywhere < 4G worked, the only change that was needed was to relaxy the 896M hard code. In one test they had a kdump kernel loaded above 2G.
