Cisco VPN Client on FC2

[Rich Renomeron]

I have version 4.0.3 of the Cisco VPN client, and it seemed to install 
fine (including compiling the necessary modules) under FC2.  However, 
when I try starting the "vpnclient_init" service, it barfs like this:

[##root at pooh## /etc/xinetd.d/] /etc/init.d/vpnclient_init start
Starting /usr/local/bin/vpnclient: insmod: error inserting 
'/lib/modules/2.6.5-1.358/CiscoVPN/cisco_ipsec': -1 Invalid module format
Failed (insmod)

Googling turned up nothing other than an unanswered post on LKML in 
April.  Searching this list didn't turn up any discussion of this 
problem.  Any idea what's going on here?  (Even explaining what might 
cause an "invalid module format" might help.

Thanks,
Rich
