Just a little update here...

I saw that 2.4dr6 was out, so I tried it out.  I still have the same problem 
with a 2.4.31 kernel:

 kernel: klips_debug:ipsec_rcv: IKE packet - not handled here

However, the good news is that the kernel works with 2.4dr6!  No more 
kernel oopses and I haven't experienced any NAT-T issues yet.  I haven't done 
any extensive testing with it yet, but at least the tunnels come up and I can 
connect to hosts behind the GW from a RW behind a NAT device.

Hopefully, this will help pin down the problem in the 2.4 kernel.

Keep up the good work!
