By looking at the code the answer is probably yes: ka43.c shows:

static void
ka43_reboot(arg)
        int arg;
{
        asm("movl $0xc, (%0)"::"r"((int)clk_page + 0x38)); /* Don't ask */
        asm("halt");
}

There are common routines to deal with halt/reboot "correct" way, 
but by some reason ka43 don't use them. (generic_halt/generic_reboot).
It may just be a "lack of test machine" reason.
You could try to change to use them and if they work I can check 
them in.
