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! :)
