$ cat /sys/devices/system/clocksource/clocksource0/current_clocksource tod (That's from 2.6.26.)

I already did something similar. Did you see my follow-up mail?
I added: + if (unlikely(clock->xtime_nsec < ((s64)xtime.tv_nsec << clock->shift))) + printk("Negative result: %llu - %lld\n", + (unsigned long long)clock->xtime_nsec, + (long long)((s64)xtime.tv_nsec << clock->shift));
Which resulted in: Negative result: 166039808000 - 166039808256
Would you still like me to try your patch?
Cheers, FJP
