loading kernels with different LMA and VMA

[rogelio]

How do we load a kernel linked at say 0xf0100000? i tried doing that with a 
custm ldscript. I set the Load address at 0x100000 and the VMA at 0xf0100000. 
When it try loading the kernel Grub says that it cannnot load below 1 M is this 
a bug? Or an unimplemented feature. It looks like the only way i can remap a 
kernel to a higher virtual memory is to use the gdt otherwise i have to 
relocate all symbols in my kernel (argh).
