I put together a little system like this for someone before. There are
several devices on the market that allow you to send X-10 codes via
serial. Here's one:

Here's one in kit form:

I can't find the website for the one I used, but the one referenced above
is very nice. You'll need an X-10 AM466 Appliance Module to plug the
modem into.
You'll need to write some sort of script on your firewall. I wrote one in
Perl that pings a known good site. It allows a couple retries at a
configurable interval before it goes ahead and power cycles the modem.
Let me know if you want it and I'll send you the script. It's very brief
and uses the pretty poorly designed Device::Serial Perl library.
