can you also check if echo mem > /sys/power/state works ? Don't forget
to enable UART wakeups with:

echo enabled > /sys/devices/platform/omap_uart.2/power/wakeup
echo enabled > /sys/devices/platform/omap_uart.2/tty/ttyO2/power/wakeup

before trying to suspend. Another cool test is rtctest (since our RTC is
part of TWL). It worked fine on my two platforms. Attached you will find
the sourcecode for rtctest.
