To make matters worse, we are starting to see a number of vendors that use multiple CPU architectures with the same I/O devices (e.g. Renesas, Freescale, Xilinx, TI, ...). Not sure if any of these use the same cpufreq register on more than one architecture, but it's quite likely to happen at some point.
