Generally this is done with a physical jumper on the board instead.
You'll find it near to the bridge chip, which is almost always by NEC.
Another technique to slow the bridge down is to insert a regular PCI
card in the other slot (these bridges tend to offer 2 or 3 slots). As
the weakest link, it'll drag everything down to 33MHz.
An old PCI-X 66MHz-only card may prove helpful here as well. You don't
have to drive it in any way; getting power to it is sufficient.
