What are the differences betw= een=20 both tables really? also, how exactly can I use ACPI throttling? because with the speestep dr= iver, I=20 can't go below 600MHz, but 12% of maximum frequency is 180MHz which I can= reach=20 using ACPI throttling. care to comment? >=20 >>are you completely unable to use speedstep-centrino and/or ondemand >>speedfreq governor? >=20 >=20 > Yes.
