LED notification

[nickd]

No. You can get it to stay on but not flash, and this will kill the 
battery. Here's what Andy (kernel dev) 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.
