idle=poll does seem to fix the major clock drift problem. There may
still be an issue, but it's much smaller:
2.6.14-mm2-todb10:
14 Nov 21:50:57 offset: -0.025373 drift: -22404.0 ppm
14 Nov 21:51:59 offset: -1.577053 drift: -24985.4603175 ppm
14 Nov 21:53:00 offset: -3.104569 drift: -25012.9032258 ppm
2.6.14-mm2-todb10 with idle=poll:
14 Nov 21:37:59 offset: 5.9e-05 drift: 63.0 ppm
14 Nov 21:39:00 offset: 0.003207 drift: 51.7903225806 ppm
14 Nov 21:40:00 offset: 0.012048 drift: 98.7868852459 ppm
14 Nov 21:41:00 offset: 0.020439 drift: 112.324175824 ppm
14 Nov 21:42:00 offset: 0.023596 drift: 97.520661157 ppm
14 Nov 21:43:00 offset: 0.026723 drift: 88.5 ppm
14 Nov 21:44:00 offset: 0.029856 drift: 82.4861878453 ppm
14 Nov 21:45:01 offset: 0.033036 drift: 78.1087470449 ppm

I just hope it helps! :)
