Actually the change happens between kernel version 2.6.15 and 2.6.16.

The timestamp optimizations are older. Don't remember the exact release,
but earlier 2.6.

What I'm saying is that, with the same Config file, some Kconfig option 
changed between 2.6.15 and 2.6.16, that made my system use pmtmr for high-res 
timesource instead of TSC.

And
is a result of Andi's changes to arch/x86_64/Kconfig and
drivers/acpi/Kconfig, which "allows/activates" the use of the timer on
x86_64.

Not sure what you mean here?

I think, that the changes you made to the files "arch/x86_64/Kconfig" and 
"drivers/acpi/Kconfig", caused this change...
