- add detection and initialization of a framebuffer (currently RGB color mode is assumed)
- add simple 8x8 fonts
- add logo drawing functionality
- add console output to framebuffer video memory (this allows to use KTF on UEFI systems without serial)

the official multiboot.h file we use uses ASM_FILE to distinguish between C and asm. We use __ASSEMBLY__, but I do not want to modify the original file.
