Some of the NitrOS-9 boot modules just do an leas -256,s for L2 and 
it seems to work fine.  I was just wondering if I can do an -512,s 
without running into something.
If it was proper to request the memory formerly, then I'd think it 
would be done this way in all the NitrOS-9 boot modules, or the 
boot_common code, that is.
