Most customers would be very happy when their I/O is so fast that it bottlenecked by 1 GB/s full-duplex DMI ;)
On the serious note, the rare customers who are going to use San Clemente boards for heavy-duty I/O anyway will plug a RAID controller in one of x8 PCIe ports. I suppose that on more "serious" chipsets based on 632xESB Southbridge they will do exactly the same. At least that's a way both Sun (x4250) and HP (DL380) build their database-oriented machines.
