+Now memory limits are not in concern. No any restrictions on placement
+and sizes of code/data. It would be an idea to move PMMM code from kernel
+into /boot to use low memory somehow, then remember that upper 64k are
+used by apm, so do not grow too much... Low 64k are used for real mode
+IDT, BIOS data, stack for /boot, so stack is big enough (about 60k).
+All the magic w/ prot-real mode interface now in one place <libsa/gidt.S>.
+BIOS (and DOS soon) interrupt entry points are now just as simple as
+they are in real mode (just use a macro BIOSINT, which shifts int#
+by 0x20, that all! ;).
