I am not sure what you mean with "long-in-the-tooth" (lack of English),
but 66 MHz PCI bus speed is one of the more modern and faster PCI types
and mostly found on server boards (often enough 64bit wide). 33 MHz is
still pretty standard nowadays, though there are x times faster PCI
specified already.
He said PCI bus speed and not system bus speed.

specification | bus width | clockrate | datarate | signal voltage | max.
device

PCI 2.3 | 32 | 33 | 0,133 GByte/s | 5V | 6
PCI 2.3 | 64 | 33 | 0,266 GByte/s | 5V | 6
PCI 2.3 |32 | 66 | 0,266 GByte/s | 3,3V | 3
PCI 2.3 | 64 | 66 | 0,533 GByte/s | 3,3V | 3
PCI-X 1.0 | 64 | 66 | 0,533 GByte/s | 3,3V | 4
PCI-X 1.0 | 64 | 100 | 0,800 GByte/s | 3,3V | 2
PCI-X 1.0 | 64 | 133 | 1,066 GByte/s | 3,3V | 1
PCI-X 266 (2.0) | 64 | 133 DDR | 2,133 GByte/s | 1,5V | 1
PCI-X 533 (2.0) | 64 | 133 QDR | 4,266 GByte/s | 1,5V | 1

(hopefully wrapped readable)
