No, I cannot. This must be found out experimentally. I just warned you

EBS makes mount really faster. But then the JFFS2 checker is working, 
and in case of NOR+EBS it will work longer and eat more CPU. JFFS2 
writers are blocked while the checker is working, so it may slow down 
the boot process. That's the theory, experiments are needed.
