While, yes, 2.2.x may be preferred, staying with 2.2.x is not
necessarily worth it at this time and in your case. If the driver was
in 2.2.x, that's what you would install. But as the driver is not
there, it's easiest for you to go with 2.4.x which Owl supports as
well and ensure you keep it up to date (the latest 2.4.x-ow patch).
If you pick Linux 2.4.x, you absolutely need to use 2.4.21-ow2
currently. (For 2.2.x, as old as 2.2.22 which was released last year
is still reasonable to keep on some existing installs. You can't do
that for 2.4.x, too many 2.4.x-specific critical security holes have
been fixed since then.)
As for using ipchains, they work (somewhat) with netfilter in 2.4.x if
you build the kernel with that feature.
We do plan to package iptables and make 2.4.x kernels the default
(while leaving support for 2.2.x as well) for Owl 1.1. Then drop
support for Linux 2.2.x in post-1.1 Owl-current (probably not very
soon, but it will happen eventually).

I'm not familiar with that driver and can't answer your question
without looking into it myself.
