The bug linked was in fact my problem, and after forward-porting the
patch to 2.6.29.4 (which required manual patching for one hunk --
luckily this was straightforward) my system boots perfectly on battery
and AC.

Many thanks all, this was the only issue I've had with the latest
kernels.  I'm very happy that it's out of the way!

Cheers,
