how to export *some* categories of posts from WP 1.5 to WP 2.0

I have an XML export for a category you set at wp_config.php but it is for WP 2.0 here

The good news is that all you have to do on 1.5 is change one line on Eric Pierce’s Export script

On Eric’s MT.php change the SQL query to say which category you want. If you wanted Category 99 for instance you would do:
$query = “SELECT $wpdb->posts.post_date, …yada..yada..yada..JOIN $wpdb->categories ON ($wpdb->post2cat.category_id = $wpdb->categories.cat_ID) WHERE $wpdb->post2cat.category_id = 99 “

You can do a similar change on his SQL.php to get an SQL Export for the cat you want
