Darn it!

You are absolutely correct, /tmp was on /, ext3 builtin, ext2 as module, so 
it was really still ext3. /bin/mount lied to me. When I moved /tmp to its own 
partition, really ext2 this time, things stopped misbehaving. That ext2/ext3 
thing was the very first thing I tried, wasted a lot of time :-(

Does this bit mean the report was still somewhat useful (for fixing either 
ext3 or the overcommit accounting) though, or was it already well-known?

Well, anyways, thanks heaps for the explanation, was going slowly mad here ...
