Just to try things out, you could try to add to locore.s:
	lea    #0xfffc00,%a0	| Switches card ON
	movb   #3,(%a0)		| via RST signal
	movb   #214,(%a0)	| on keyboard ACIA
	bclr.w #2,0xff8007	| Blitter clock = BUS clock/2

Just before the lines:
	/*
         * let the C function initialize everything and enable the MMU
         */
	jsr     _C_LABEL(start_c)

I just translated the assembler statements. Note that the Falcon I/O area
is at 0xff8000 and not 0xffff8000 since the MMU is disabled.

If this works, next item is how to properly detect the card.

Leo.
