It depends whether the CPU is checking the reserved flags and faulting 
if any are set, rather than ignoring the global flag....
A quick thing you can try is to define _PAGE_GLOBAL in 
include/asm-x86/page.h to be 0 rather than 0x100U. This will stop us 
trying to use pge in any page table entries.
The crashes you are seeing are so weird and early that it must be 
something stupid like this that is causing you problems.
