hey, Im trying to get put of first 4 meg, however i get problems with idt, I think. Is there a condition for idt's place in virtual memory? I mean should it be mapped onto itself or etc?

No - the IDT can be anywhere. I wouldn't recomend making the IDT cross page boundaries though, and I'd make sure it has 8 byte alignment (for performance reasons).
