I do not have a Cisco Concentrator, but I do have a Cisco PIX 515E which
I use the Cisco VPN client to connect to with FC4.  I have had not had
the problems that you are describing at all.  The Cisco VPN software
that I use is:

vpnclient-linux-4.6.00.0045-k9
and I install the patch
vpn-2.6.10-interceptor.patch
The patch basically lets it build for the newer kernels.
