There is an ultra-low power sleep mode described in Philips' application note AN10022_1 that I think requires the use of H_WAKEUP. FYI, on my platform with USB operational the current draw @ 5V is 326mA, in normal isp1160 suspend this drops to 302mA (saving 23mA) and in this deep sleep mode it drops to 288mA (total saving 37mA, 14mA more than regular sleep).
