Thanks a lot.

About three weeks ago I started getting boot problems which may or
may not be acpi-related. I reported them on freebsd-current@ in
the thread 'geli boot issues with recent kernels', the message id
is <20100918155100.5b74cdb2 at r500.local>.
 
I applied avg's patch yesterday and the system (ThinkPad R500)
bootet successfully from battery, three times in a row.

Of course this could just have been an coincidence and as I csup'ed
before applying the patch the problem may also have been fixed in HEAD
already, but I didn't see any obvious fixes there.

I'll probably have time for some more tests this weekend.
