My understanding is that most commercially sold Freerunners are revision
6.  Is that incorrect?  If it is correct then according to what someone
else posted, the AUX light should only consume around 6mA.

I too would be willing to live with reduced battery life to have this
feature.  Like Steven said, it's not likely that the light would remain
lit for too long without me noticing it, so the decrease in battery life
would certainly be less than 50%, maybe even only reducing it by 10% or
20% during normal usage.  And if these recent reports of adding a 10uF
capacitor to resolve ticket #1024 are true, then that could mean that
even in a worst case scenario the device could still remain suspended
with the AUX light illumated for perhaps 50 to 70 hours.

For those with revision a5 or who don't want to risk/bother with lower
battery life, this feature could be a configuration option.  Also, I
don't know what drain it puts on the battery, but waking the system just
to check if a call or SMS was missed surely has some power consumption
consequences that can't be totally discounted in this equation.
