Actually, dividers normally are established by the chipset.
The smallest dividers on the BX chipset were 1:4 for the PCI and 2:3 for the AGP. This is why BX @ 133MHz could still run PCI devices okay, but many vid cards couldn't handle the 100MHz AGP.
The VIA 133MHz chipsets and the Intel i815 added 1:2 AGP, which AFAIK normally kicks in at either 120 or 124MHz bus on most boards and stays there for any higher speeds.
Why BX happened to have a suitable PCI divider, but no suitable AGP divider, for 133MHz I have never heard explained, though...
