Loading kernel at a higher physical offset

Hi All,

I have a Intel Core 2 Duo processor.
I want to run a kernel in a higher physical offset. i.e. If I have 1
GB of memory, I want to give upper 512 MB for loading another kernel
on second core. Is this possible for x86 or x86_64 architecture?

I have read that kexec uses a mechanism which loads a crash kernel at
a reserved space in RAM. Can this mechanism be used to achieve the
above goal?

Thanking in anticipation,
Swapnil Pimpale.
