Subject: Paging and heap rewrite

VESA drawing causes a Page fault because it tries to use a pointer to the framebuffer which was created before the paging has been initialized. If the resolution is set after the paging has been initialized the CPU throws a triple fault because the int32 call can not happen with paging turned on. To be fixed soon!
