Really? What are PCI bus transfer rates up to these days? I havent looked into it in quite a while.

Your average 33mhz PCI bus has a paltry maximum bandwidth of 1 gbps. Full-duplex gigabit routing on more than one interface pretty much requires PCI Express. Here's a little table:
PCI32 33MHz = 133MB/s PCI32 66MHz = 266MB/s PCI64 33MHz = 266MB/s
PCI64 66MHz = 533MB/s
PCI-X 133MHz = 1066MB/s
Also gigabit routing on your average unmodified linux distribution requires a VERY hefty CPU to keep up, even just with two or three gigabit interfaces.
