Because this card is designed to run in a 66MHz pcibus or standard 33MHz
pcibus, but the idebus/bridge is clocked at double pump or 1:1 depending
on the busses 64-bit/66MHz, 64-bit/33MHz, or 32-bit/33MHz

This is were it gets messy........so I do not have an answer that I valid
at this point, however I do know that 66MHz clocking is about to become
standard...
