For what its worth, most Linksys routers these days run VxWorks, not
an embedded Linux. (Apparently they can put 8MB or so less RAM in
them with VxWorks.)
Another option you could try is to set up your own DNS server (if you
install your own firmware onto that Linksys router you can probably do
this.) Then, you can whitelist specific DNS domains, e.g. google.com,
wikipedia.org, etc. (I won't even suggest you try to come up with a
comprehensive list of domains to blacklist.) Everything else can be
redirected to 127.0.0.1. The advantage of this is its simpler and
very powerful. The downside is you'll be blocking access to a fair
number of legitimate sites (but probably not as many as you'd think.)
