Many screen readers for the blind, can't deal with DOM changes that happen
after an onLoad. I'm not saying that javascript in and of itself makes a
page inaccessible, I'm saying that the requirement for a page to meet either
508 or WCAG accessibility guidelines require that the page work with
javascript disabled.
Section 508 has two paragraphs that can be construed with this in mind for
DHTML /Javascript
(d) Documents shall be organized so they are readable without requiring an
associated style sheet.
(l) When pages utilize scripting languages to display content, or to create
interface elements, the information provided by the script shall be
identified with functional text that can be read by assistive technology.
WCAG is more direct.
6.1 Organize documents so they may be read without style sheets. For
example, when an HTML document is rendered without associated style sheets,
it must still be possible to read the document. [Priority 1]
6.3 Ensure that pages are usable when scripts, applets, or other
programmatic objects are turned off or not supported. If this is not
possible, provide equivalent information on an alternative accessible page.
[Priority 1]

Sandy...
How is having javascript on your website causing a site to be
"un-accessible"? That makes no sense.

I can tell you that section 508 and the WCAG both have a requirement that a
page be able to work without javascript in order to be considered
accessible. If you are required to build accessible web pages, then that is
a major consideration.
However, IBM demonstrated an accessible javascript which the new Firefox
beta is supporting. Once that is widely available, I believe that the
javascript disabled rule for accessibility will be deprecated.

I've never supported non-JS.
Cross browser JS, yes, but building a non-JS version...? Then what? A
version that works in Netscape 2? Maybe a Lynx only version? There comes a
point when you can't cater to the lowest common denominator.
IMO, JS is pretty darn common place. Those afraid of JS and cookies should
probably stick to sneaker net and snail mail :)
