I wonder is this is x86_64 only problem?

I'm having the same problem on dual xeon 1.8GHz i686 with HT enabled, kernel 
2.6.14.2-4smp. Clock runs twice fast. Previously I was using 2.6.11 kernel 
with no such problem.

cmdline is: acpi=ht nmi_watchdog=1

Unfortunately I can't do any testing right now on this machine but I'll try 
acpi_skip_timer_override cmdline option as soon as I can.
