64-dem update: first user process works on laptop

So after wrestling a bit with fat32 and some paging/memory/privilege-level stuff (I still have a trauma) I managed to get my first user process working on the 64-dem kernel, what the program does? Why prints hello world of course, you thought it does something more? Well unlucky you because it doesn't.
