Please check arch/ppc/kernel/m8xx_setup.c in your kernel tree. Look for

static void
m8xx_halt(void)
{
    m8xx_restart(NULL);
}

I changed that so my power supply gets switched off when shutting down the system.

So write your own version of halt and do a

         ppc_md.power_off                = imcDev_power_off;
         ppc_md.halt                     = imcDev_halt;

in you board initialisation code.

Good luck,

Steven
