Nasser's article is wrong in that the kernel isn't using the hardware- supported watchpoints (on any architecture) -- fortunately, that's really ancillary to the crux of the article.
Eric's article (and the next one http://blogs.sun.com/eschrock/date/20040717) accurately describes how watchpoints are implemented and some of the improvements he made in Solaris 10 to increase performance.
