I made some progress in my understanding of the situation: the
problem happens when booting from EFI but not from BIOS. And
the difference is taht paging is already enabled when booting
from EFI. 

I also note that when we do not use multiboot with EFI, we go
through src/sys/arch/i386/stand/bootia32/startprog32.S which 
disables paging and PAZ before starting the kernel.
