Here's my copper init routine... Just slightly different i guess.
Code:

; Initialize the Copper list

INIT_COPPER1:
move.l MEMCHK2_COPPER1,a1
move.l a1,d4
move.w #BPLCON4,(a1)+
move.w #$0011,(a1)+
move.w #FMODE,(a1)+
move.w #5,(a1)+
move.w #DIWSTRT,(a1)+ ;
move.w #$2cbe,(a1)+ ; ;
move.w #DIWSTOP,(a1)+ ;
IFNE DEBUG_BORDER_ENABLE
move.w #$ffd2,(a1)+ ; ; 1b2 - be = f4 (244) pixels (debpt =$ec)
ELSE
move.w #$ffb2,(a1)+ ; ; 1b2 - be = f4 (244) pixels (debpt =$ec)
ENDC
move.w #DDFSTRT,(a1)+ ;
move.w #$0038,(a1)+ ; 3c
move.w #DDFSTOP,(a1)+ ;
move.w #$00d0,(a1)+ ; a4
; Initialise Normal Sprite DMA
