  A 32bit/33Mhz PCI bus might theorectically do 1Gb/s. However, there are
a great number of practical reasons why you won't get more than half that.

  A 64bit/33Mhz PCI bus that I had experience with didn't get more than
500Mb/s for reasons relating to FIFO sizes on PCI targets being too small
to sustain the bursts involved. (There is also a PCI churn problem with
access to receive descriptors). These problems were more local.

  [We had electrical problems with using a 64bit/66Mhz slot.]
