Thank you, Antonio. At least now I have something to investigate. From 
dmesg I found:

cisco_ipsec: version magic '2.6.25.3-18.fc9.i686 SMP mod_unload 686 
4KSTACKS ' should be '2.6.25.4-30.fc9.i686 SMP mod_unload 686 4KSTACKS '

So somehow, it still thinks it has and old kernel. Maybe a 'make clean".?



Okay, that was it, I think. I should know better than that. Really bad 
build procedures to not do a "make clean" before you rebuild. I should 
note, however, that you don't want to change "EXTRA_CFLAGS" to 
"EXTRA_CPPFLAGS", in this instance. This cause a whole raft of errors. I 
set it back.

Thanks for your assistance.
