FWIW, I'm running Debian unstable on a Thinkpad T60 and have the
same problem.

Yep, I get those same messages.

I have worked around it by having ntpdate run after bootup. I'm
lazy and that was easier than trying to do the right thing
(finding and fixing the real cause of problem...).

Same here.

Well, I've had the same problem since first installed Debian on
this machine (5 or 6 months ago, I guess). And Etch is supposed to
be approaching stability, so if the cause of this is in Etch and
it hasn't been noticed and fixed by now, I think you may find
yourself waiting a long time (unless you do what I haven't done,
and report it to Debian as a bug).

Only thing I can suggest it setting up your environment so that
ntpdate runs after the boot sequence is done (which is just a
workaround, not a solution).
