* timer/timer.c: Enhance to use either interupt-based timer functions on older CPUs or to use TSC-based timer functions on more recent (Pentium and above) CPUs. The decision is made in Timer_initialize function when it is called for the first time based on a result obtained from cpuid instruction during the BSP initialization phase. During the first call, there are also late bindings to the implementation functions initialized to appropriate values.
