Networks PCI ADSL (Bewan chipset) modem...

Has anyone had any luck getting a PCI ADSL (Bewan chipset) modem to work under OpenBSD? I'm fed up of having to turn apache off when I'm mid-way through a game of BF2 just because someone wants to view my website (it's hosted locally). BSD reputedly does a good job of traffic shaping which should solve this.

I'm currently running a smoothwall box, but the traffic shaping mods I've tried for it have never worked

Any advice would be very gratefully received!

Cheers,
Jon
