Somebody in the thread at some point said:

It's possible to leave a GTA02 LED lit during suspend, but without
waking-suspending each time, from PMU RTC interrupt for example, not to
have it "blink".  It sounds a pretty hairy thing to attempt and it will
halve suspend life at least to have an LED lit during it.
