I spent the better part of an afternoon fighting this problem (or one
much like it) on my laptop.  Free nv driver works, but the restricted
driver causes really obnoxious stalls, to the point where the app dims
out multiple times for several seconds on some pages.

Page which demonstrates the behavior most severely (ironically):
http://mozillalinks.org/wp/2008/02/firefox-3-ultimate-feature-performance/

I saved a local copy of the CSS, and did a binary search to find the offending 
CSS.  Here it is:
#page {
        background: url(images/structure/backgroundColumns.png) repeat-y;
        background-position: 3px;
        margin-top: 50px;
        width: 970px;
        margin-left: auto;
        margin-right: auto;
        border: 1px solid #D9D9D9;
        z-index: 10;
        }

Readding pretty much anything on the #page entity causes rendering
stalls.  I started readding individual lines from this chunk, but there
didn't seem to be one particular culprit.  It seems that most/all of
these lines contribute to the sluggishness somehow, to varying degrees.
