Comment(by SteveBooth):

 I figured it out, and it's REALLY arcane.  Get some Coke.. this is going
 to take a bit.

 When the root index.php file runs, it requires blog-header.php.  When this
 runs, it requires 'template-loader.php.  Line 7 in 'template-loader.php'
 which is very nearly the first thing this module does is:

         do_action('template_redirect');

 This calls 'redirect_canonical' in canonical.php.  No $args have been set
 up for the template_redirect and the $requested_url parameter to this
 function is null.

 This causes the following code, on line 45, to execute:

         if ( !$requested_url ) {
                 // build the URL in the address bar
                 $requested_url  = ( !empty($_SERVER['HTTPS'] ) &&
                    strtolower($_SERVER['HTTPS']) == 'on' ) ? 'https://' :
 'http://';
                 $requested_url .= $_SERVER['HTTP_HOST'];
                 $requested_url .= $_SERVER['REQUEST_URI'];
         }

 And herein lies the problem.  My site is hosted on a Concentric Unix
 server. PHPInfo returns the following:

 PHP Version 4.4.8
 System: SunOS www.stevenmbooth.com 5.10 VDE sun4v
 (MySQL is 4.1.22, but it's not germaine here)

 And here's the bottom line. My wordpress home directory is
 'http://www.stevenmbooth.com/wordpress'. $_SERVER['HTTP_HOST'], above,
 returns 'www.stevenmbooth.com' and '$_SERVER['REQUEST_URI']' returns null,
 and this produces The INCORRECT PATH.

 These results cause the above code to construct the url
 'http://www.stevenmbooth.com' as the redirect URL, and the browser
 immediately redirects to my root page, which causes my old index.html web
 site to initialize (I'm installing the WP site in the directory
 stevenmbooth.com/wordpress'.

 SO... Either that redirect line at the beginning of template_loader is
 completely wrong (doubtful), or we need to use something other than
 HTTP_HOST to detect the root directory for WP (see http://www.nabble.com
 /When-HTTP_HOST-does-not-point-to-the-blog-td18097138.html ).

 OH.. and I do believe this is a problem in 2.8.x as well, and that's why
 2.8.x doesn't work for me.

 So, you see, the problem was actually with WP's interaction with my Apache
 server, and not my site or my templates.

 The question is... what do we do to fix this?  What's the right way to
 detect the home install directory for WP?  Assuming it's HTTP_HOST seems
 to be incorrect, here.

 Geez.  I wish I could charge you for the 12 hours it's taken me to find
 this.
