Code:
section .text				;section declaration

			;we must export the entry point to the ELF linker or
    global _start	;loader. They conventionally recognize _start as their
			;entry point. Use ld -e foo to override the default.

_start:

;write our string to stdout

        mov     edx,len ;third argument: message length
        mov     ecx,msg ;second argument: pointer to message to write
        mov     ebx,1   ;first argument: file handle (stdout)
        mov     eax,4   ;system call number (sys_write)
        int     0x80	;call kernel

;and exit

	mov	ebx,0	;first syscall argument: exit code
        mov     eax,1   ;system call number (sys_exit)
        int     0x80	;call kernel

section .data				;section declaration

msg     db      "Hello, Gollum!",0xa	;our dear string
len     equ     $ - msg                 ;length of our dear string

The only one who can say if it works or not is you!
You have to assemble the hardware you designed and see if it works or not. You are asking us if a piece of code works, but the software works with the hardware.

You have to initialize the uC, set the interruptions, set the P0,P1,P2 and P3 as inputs or outputs... A bunch of things are missing. But I see no problems with the sintax you posted, I cannot go any further due the lack of information you gave us.
