I just came back from Aruba Networks' AirHeads conference, and they are recommending to customers to do the exact opposite: run your data on 802.11a and voice on 802.11g. This way, you get 54mb speed for your data, and by using only 802.11g phones for voice, you'll get the full 54mb all the time.
Remember that as soon as one "B" client associates to a "G" access point, it cuts all throughput in half or more. If you only have "G" phones, and don't allow "B" connections, you end up with two networks with full bandwidth. I'm not sure I explained that clearly, it's late and I just flew in.

That helps with the co-channel interference. With the additional 200+ MHz that the FCC added, and the upper UNII, it's possible to have many more channels. Another reason to seriously consider 802.11a for data deployments, and 802.11 b/g for voice.
