Same here: php 5.3.1 (suhosin patched)

Occurs every six years, then in the following year the week is off by -2

A quick search revealed an issue with similar timing, due to daylight
saving time: http://bugs.php.net/bug.php?id=29065

It is suggested in that bug report to use gmmktime or gmdate instead.
Is that an option for you?

date("W",gmdate(0,0,0,01,1,2010));
seems to work as expected
