UPDATE: Hmm, it looks like the the stats are still broken in Tiago's version. I will look at the his sources and try to find what's wrong. Till that time, better use the module version that is attached here.
UPDATE 27 August, 2010: the patch has been incorporated in the new 1.4 version of the milestone-overclock module by tiagosousa, therefore this modified version is no longer needed.
This patch fixes two issues of the original overclock module (v1.2):
1. broken CPUfreq statistics
2. freq_table_addr and mpu_opps_addr not set by echo to
/proc/overclock/omap2_clk_init_cpufreq_table_addr (Issue 30)
