fprobe-ulog fixes this. From the http://fprobe.sourceforge.net/ front page:

	fprobe-ulog - libipulog-based fork of fprobe. It obtains packets
	through linux netfilter code (iptables ULOG target). The main
	advantages of this version are native input/output interface
	SNMP-index support and significant performance benefit. Of course,
	this version work on linux only.

We have used it here for a few years and have been quite happy with it.
