Let me preface the following, by letting you know, I'm not trying to be argumentative. :)

I should also note; that I'm speaking from a *BSD box. So this might explain differences.

'nuff said.
So my experiences seem to be a bit different. For example. My last log entry (somewhat abreviated):

:8090 tcpflags 0x2<SYN>; tcp_input: Connection attempt to closed port
[download]

I cant speak for Linux, or OSX, for that matter (altho OSX uses BSD). But at least on BSD, it seems like I could get that sort of information. I'll look a bit deeper, and see if I can get the kind of output the OP's looking for.
