Maybe I am misunderstanding what you are getting at but I just checked two of the top sites and one uses html and the other uses asp. Neither has the index page listed at all in the site: command search but both their mysite.com/ and their mysite.com/index show their same pr. I would think some other problem must exist. perhaps in the way their 301 is placed for www to non-www.
And one interesting side note: the one with html has all it's pages except two supplemental and the other has quite a few but lots not. The supplementals don't seem to affect rank. Even with all my pages except the index page on one of my sites gone supplemental, it is climbing in the serps daily.
