The linksys WAP11 supports a bridge function, but instead of using the WAP11 in bridge mode, I was going to put it in infrastructure mode and set it up in a window at my moms and put the wireless adapter on my knoppix box in a window at my house, and just have the knoppix box be a client off of the WAP11.
I just didn't want to have a seperate subnet on the eth0 side of my knoppix box. I would rather have eth0 and wlan0 be on the same subnet and have the traffic from my house to her's pass transparently through the knoppix machine.
