If you really want this, patches to do so have been in hap-linux (2.2.x) for a while, and they were picked up by grsecurity (2.4). We both log SIGSEGV, SIGBUS, SIGABRT, SIGILL currently; you could add others if you desired. The logging is rate-limited to reduce log-flood opportunities (though as others have mentioned it's quite easy to flood logs through other means).
