One thing to remember is that the activate hook is dependent on the plugin name.  At first, I was
confused because I'd installed the plugin to its own directory, but not included that in the plugin
hook.  As in using:

add_action('activate_pluginname.php', array(&$this, 'activated'));

instead of:

add_action('activate_pluginname/pluginname.php', array(&$this, 'activated'));

Where the plugin files were in the directory 'wp-content/plugins/pluginname/'.  Other than them
installing to the wrong directory, no idea why it might be failing.  In any case, I decided to add
my tables on the first view of an options page, then used the activate hook to redirect the user
straight to that page when the plugin was first installed, instead of going back to the plugins
page.  That way, even if the activation screws up, my tables will still be created when they look at
the config page.
