Tested and didn't get those errors. Then compiled 2.6.21.3 vanilla, as thought, it was kernel problem, got those errors again. Seems that Athlon has some kind of troubles with new kernels. Namely in original centos kernel there is pentium pro optimized... Ok, next step was, I stopped cpuspeed from services, edited ntp's drift file into 0.000 and restarrted ntpd, no errors after that. Time is well in sync and not mentionable drifting in sight...
