well, does the system have any early boot detectable property? Such as a 
DMI signature? That way there would not be anything truly dynamic about 
the PIT rate - we'd just set a new pit_tick_rate variable to a 
non-default value very early during bootup, on an RDC system.

On usual PCs it would stay unmodified, at the default 1193182 value.
