The BX boards run the PCI and AGP buses at 33MHz and 66Mhz respectively
when using the 100MHz front side bus speed.

Exactly. At 100 MHz, the PCI bus is achieved by dividing by three
instead of two. One problem could arise from your processor, though:
some Intel CPUs don't allow using a lower multiplier. The celeron A is
one example - you can run it at 4.5x66=300 (Intel's math, not mine :)
or at 4.5x100=450 MHz, but you can't set it to, say, 3.5x100.
