Disabling 64-bit DMA on atl1?

Jeff --

Can we please get Luca's patch merged for 2.6.23? The bug is a data corrupter,
and the workaround doesn't cost us much. Both Jay and I have already acked it.

We'll do it "the right way" once Atheros tracks it down with hardware
analyzers, but for now, let's fix the data corrupter.
