I've tried searching for AAT1275 replacement, and no luck so far. However, at least TI has some power controllers able to provide at least 400mA. Others can go
up to 1-2A, like USB hub power supplies.

I wonder if this is a good idea to use a USB integrated HUB and perhaps leave some pcb traces so one can connect more devices to it.

Depends a bit on what we do want - just a 5V, 500mA-limited power supply ?

Hard. Those are typically short life components, maybe we should just replace them with similar (on purpose) parts. PMU should be fairly easy, GPS perhaps not.

I hope so too. And time to revive gta02-core blog. I believe we do have again enough stuff to put there.
