I've been trying to get an accurate reading of my Raspberry Pi's MHz, since I overclocked it in /boot/config.txt

My /boot/config.txt is as following:

pi@raspbmc:~$ cat /boot/config.txt 
arm_freq=900
gpu_freq=350
disable_overscan=1

List of things I already tried:

1. Look at the /proc/cpuninfo - No MHz listed, does have BogoMIPS at 697, while CPU speed is set at 900.
2. The sysstat package - returns 0.00 MHz.
3. cpufreq-info: no or unknown cpufreq driver is active on this CPU

Any ideas?
