When the manual for your mainboard states that clock settings for setting up your CPU creates a change in the normal idebus=33MHz of any other value, then you are probablely safe. Since all 32-bit PCI busses run at 33MHz, as last thought and reported, it should not be needed to change. If I recall the idebus=XX primary use was for VLB/ISA/EISA systems, but I have been wrong before.
