It will quite likely be ignored for PCI accesses, but everything that goes through the chipset is affected by this bit. So if this bit is not set, write accesses to the bios flash will not be clocked to the SPI bus.

what have you "checked" exactly? did you try clearing the bit, issuing
SPI commands and looked at the physical bus?
it's a pity that the public data sheets do not provide a clear
statement regarding this bit.
