Hmm, they might be handy to have around in case an A5 blows up, and
mail is slow.

BallGAme ? ;-) Luckily the PMU isn't one of them ...

Oh yes. We also have "high speaker volume freezes the phone".

If there's a little bit of space, it may be pretty easy to do this in
the SMT process, by shifting components a little so that they can
share pads. Surprisingly, this sort of hack is actually supposed to
yield perfectly good connections.
By the way, do you have a picture of your rework ? My GTA02v5 might
arrive today, and a bit of soldering may be the perfect welcome :-)
