As I understand it (from work I was doing on IRQ blocking measurement)
*wrong* "timebase-frequency" properties were common in earlier Mac OF.
AFAIK Linux does not rely on this properties (from what Ben H has told me).
I can post some very simplistic user-space code to measure the TB frequency
(close enough) on the linux side if anyone wants it (basically doing the
same trick of calibrating it from gettimeofday).
ciao,
Iain.
