 "idebus=xx"		: inform IDE driver of VESA/PCI bus speed in MHz,

			  where "xx" is between 20 and 66 inclusive,

			  used when tuning chipset PIO modes.

			  For PCI bus, 25 is correct for a P75 system,

			  30 is correct for P90,P120,P180 systems,

			  and 33 is used for P100,P133,P166 systems.

			  If in doubt, use idebus=33 for PCI.

			  As for VLB, it is safest to not specify it.

			  Bigger values are safer than smaller ones.
