the code is simple. there are two functions we are interested in changing
set_max:speed() and omap2_find_address()
omap2_find_address() finds two structures that define the voltages and
frequencys that  the cpu is comfortable with. It does this by
decompiling omap2_clk_init_cpufreg_table_addrs. values in these
structures are then faked
the problem is no function like this is exported in diablo. I took a
guess and decompiled cpu_core_init but its not the same function.
as for nokias warning, i say "I don't comply with warnings", as i hold
up my 3 remaining fingers .as always suggestions are welcome
