Well the line that is printed just after when booting with nolapic is NX 
(Execute Disable) protection: active
generated by x86_report_nx().

I looked through kernel/setup.c and can't really see anything between 
setup_memory_map() which dumps the e820 map and x86_report_nx() which 
could be affected by ACPI or nolapic. BTW, I've just seen that nolapic 
is only significant on X86_32. I didn't know that.
