No problem! I enabled writing the trace data to a file and then tried
to trigger another OOM situation. That worked, this time without a
complete kernel panic, but with only my processes being killed and the
system becoming unresponsive. When that happened, I let it run for
another minute or two so that in case it was still logging something
to the trace file, it could continue to do so some time longer. Then I
rebooted with the only thing that still worked, i.e. by means of magic
SysRequest.

The trace file has actually become rather big (around 21 MB). I didn't
dare to cut anything from it because I didn't want to risk deleting
something that might turn out important. So, due to the size, I'm not
attaching the trace file to this message, but it's up compressed
(about 536 KB) to be grabbed at:

http://ftp.tisys.org/pub/misc/trace.log.xz

For reference, here's the OOM report that goes along with this
incident and the trace file:
