I took a look at it but I got the impression that the code in mach-davinci does not use your OPP library. Instead the structs that are used for the OPPs are defined locally in arch/arm/mach-davinci/da850.c. The frequency multiplier and divider values are hardcoded there and do not scale with the input clock frequency.
