drivers/video/aty/atyfb_base.c: In function 'atyfb_blank':
drivers/video/aty/atyfb_base.c:2817: warning: implicit declaration of function 'machine_is'

This is i386 build.

#ifdef CONFIG_FB_ATY_BACKLIGHT
	if (machine_is(powermac) && blank > FB_BLANK_NORMAL)
		aty_bl_set_power(info, FB_BLANK_POWERDOWN);
#elif defined(CONFIG_FB_ATY_GENERIC_LCD)

It assumes that only pmacs have backlights.
