If the API allows us to query the tsc frequency, it would simply return the same values in all cases, which we'd ignore.

The API only allows querying the processor frequency. In the constant_tsc case, the highest processor frequency is likely going to be the actual TSC frequency, but I don't think it's a guarantee; theoretically, it could be faster on normal hardware ... or slower on overclocked hardware with an externally clocked TSC.
