Trying FASM instead of TCC hybrid proved to be a good choise. Binary is layed out flat and sections are not rearranged so no need to worry about Multiboot structures moving around. 
Also managed to get paging (first 4M is identity mapped, but hey it's a start).

Switched FASM to NASM 
If I'm gonna port a C compiler I might as well use and port NASM as it 
is more widely used anyway
