I don't have a Pi running atm, but this command exists in my raspbian chroot. This is on my quad core desktop, which is currently somewhat idle so it takes in the governor setting (don't know whether this is available on the pi, i suppose not)

Another one, with some caveats: this does is not very reliable as it uses information reported by the bios and it is not available in the current raspbian wheezy repository (i'm posting because maybe it will someday):

$ sudo dmidecode  | egrep "Max Speed|Current Speed"
Max Speed: 2900 MHz
Current Speed: 2900 MHz
