Ruslan,

I can see this would be a problem for the final running kernel.
However, is 4GB sufficient for kernel loading & kernel memory discovery?

I am interested in situations were 4GB would not be sufficient.
Say, having grub2 being utilized for full device discovery for a 
minimalistic kernel...
Or, having grub2 be the minimalistic kernel...

Forgive me, I am still learning the Weirding Ways ;)

Regards,
Joel
