A small number of 486 systems use 25Mhz, some boards allow overclock at 37.5Mhz on the PCI. I've been looking at this the past couple of days for the libata via driver which I've been porting over and unfortunately having been through the Northbridge manuals I can find no way to ask the chipset what the PCI clock is set too.
