This actually should not be possible as the scroller code has been redone in the WHDLoad patch (regardless of the chipset).
Edit: But I'll check the patch code and update it if necessary, it's always possible there's a bug somewhere of course.
Code:
; rather unconventional way to fix the modulo bug on ECS machines
; but it works
move.l #$35000+$5000,$50(a5)
move.l #$75000,$54(a5)
move.w #50,$66(a5) ; skip every other line
move.w #$09f0,$40(a5)
move.w #23<<6+25,$58(a5)
.w2 btst #6,$2(a5)
bne.b .w2
