You don't *have* to use the Cisco provided client (as you already well
know) there's VPNC as well, which works *very* well under linux, and is
insanely easy to build, configure and run.

Generally, OpenVPN is a SSL VPN and Cisco uses IPSEC, but that doesn't mean
it's not possible.  Most all of Cisco's newer VPN offerings support SSL VPN.

Do you have a specific Cisco VPN device in mind? Or do you mean any Cisco
VPN device?

If you mean a VPN 3000 concentrator, I would say no.
If you mean an ASA device, I would say yes.
If you mean a IOS device, I would say maybe. (Depending on version and a
good deal of tinkering)
If you mean a PIX device, I would say maybe. (Depending on version and a
good deal of banging head against wall)

*Technically "it's not supported".   But the "not supported" tag (primarily
used to reduce costs of large businesses trying to train their
non-technical customers to use anything more complex than an off/on button)
is clearly not any limitation for linux people? *

Just go with a Cisco compatible client!

OpenConnect is still a very good product, and I would choose it over
Cisco's client any day!

Also, you can allow OpenVPN through the cisco firewall and run both IPSEC
and SSL VPN, by getting a nice OpenVPNAS Virtual Appliance, you will be up
and running in 1/2 hour, plus your users can go right to the VPN server and
authenticate and download their clients without any big fuss.  Just because
you have a Cisco VPN available, doesn't mean you must use that IPSEC
virtual private tunnel exclusively.  Once you allow SSL VPN, you can use a
quick setup OpenVPN AS Server:

Here's what the OpenVPN Access Server looks like:
