No, the _P routines won't work at all the way you write it.  For them,
you need something like

printf_P(PSTR("printf_P\n"));

Also, your printfs will be converted to puts by gcc anyway. ;-)

I have no idea about the garbage.  I get something like that if i
forget to wait for the UART being ready, but you wait correctly.

Are you sure your clock is within the allowable tolerance?
