Memory usable by the kernel
---------------------------

 MB|B     -  MB|B
000 07800 - 000 079FF   vbe mode buffer
000 08000 - 000 0FFFF   stack
000 10000 - 000 1FFFF   variables
000 20000 - 000 5FFFF   kernel
000 60000 - 000 6FFFF   ext2 buffer
001 00000 - 001 FFFFF   keyboard layout
002 00000 - 002 FFFFF   system font
003 00000 - 00B FFFFF   temp buffer (up to 1920x1200x32)
00C 00000 - 00F FFFFF   ehci TD chain
010 00000 - FFF FFFFF   loaded applications and files

In the above numbers there may be some gaps, but don't load anything there,
as it would cause unexpected results, like overwriting video low memory.
