I vaguely recall using the cisco vpn client for linux on an smp kernel
just fine, but I stopped using it years ago, as vpnc works well enough
as a replacement for it.

I do know how, but its semi-involved, and I'm afraid I'm a bit tied up
with other slightly more pressing work. Short version is that you need
to add a config-foo target in merge.pl, iirc, add that to the spec as
another Source, tweak instances of %with_up within the spec file, and
that would at least get you close.

But again, I think this is really pointless, since 1) I'm pretty sure
the cisco vpn client runs fine on smp 2) if it doesn't, vpnc works
reasonably well to replace it and 3) you can likely just boot the 
current smp-enabled kernel with maxcpus=1 added to the command line
to get up behavior if you absolutely must run the cisco vpn client in
a single-processor environment.
