Since I posted this (couple of weeks back) I've looked at logs more closely, and I don't think timeout is the issue. It looks like sometimes ppp just can't negotiate the link properly - maybe it's purely a pppd problem?

See my more recent post with log samples of 2G connections attached.

For completeness, I've attached the successful ppp negotiation for the 3G case, which I couldn't get before.
