Ben Gras 3bc6d7df06 impove memory accounting
. the total amount of memory in the system didn't include the memory
	  used by the boot-time modules and some dynamic allocation by the
	  kernel at boot time (to map in VM). especially apparent on our
	  ARM board with 'only' 512MB of memory and a huge ramdisk.
	. also: *add* the VM loaded module to the freelist after it has
	  been allocated for & mapped in instead of cutting it *out* of the
	  freelist! so we get a few more MB free..
