First, you don't need to convince me that the eminence model is lacking and that Silverman's contributions to the field have been numerous and worthwhile.
As for links--I'll list some below.
Indigo children:
http://www.awarenessmag.com/novdec3/ND3_CHILDREN_OF_NEW.HTMLhttp://www.byregion.net/articles-healers/Indigo_Children_Facts.htmlAlso, pages 112-114 of the book Hothouse Kids by Alissa Quart
Vision therapy:
This may have been discussed on the TAGPDQ list. The contention was that the GDC suggested vision therapy to a disproportionate number of clients. The people discussing it were skeptical of VT and thought that the GDC was being fringe-y for recommending it. Disclaimer: They suggested it for my son, and they were right--he needed it.
SB L-M:
The controversy here was over the use of an extremely outdated instrument. Again, I think most of what I know about this came from the TAGPDQ list. It's not clear to me that the GDC even uses the L-M any more.
Again, pages 112-114 of the book Hothouse Kids by Alissa Quart
There is also this New Yorker article, which discusses some of these issues:
