Yeah, SMP + PREEMPT

when running my stress-test on vanilla 2.6.6, the OOM-killer starts
killing things off 'correctly' and it doesn't seem to crash -- at least
I haven't run it into the ground yet.  I suppose I can try again.

gds-2.6.7-r16 dies abruptly without ever calling the OOM-killer.

I assume you're speaking of the vanilla sources?
I'll download and compile them....
