Semi-OT: Running CAT5 Cables (Stupid Question)

OK, I was pointed at http://www.linksys.com looks like they've got some good info. However, I just noticed something that has me wondering, looks like CAT5 only has 4 real wires made out of the 8 wires. So... Is it possible to run at least 10BaseT over normal phoneline cable? It just happens that a totally unused phoneline was run a couple years ago at the same time I had a work phone put in. Yes, I want to be lazy if possible. I'm assuming that if it is possible I can make a RJ11-to-RJ45 adapter and plug one end into a hub in the house, the other end into a hub in the garage. Zane | Zane H.
