nginx users with mod-rewrite urls: can you post your virtual host file?

[sub_ubi]

I'm having a heck of a time getting mod-rewrite friendly URLs working in nginx. I followed this post,

http://www.vbulletin.com/forum/forum...00#post4032700

rewrite    /threads/.*                   /showthread.php?$uri&$args     last;
rewrite    /forums/.*                    /forumdisplay.php?$uri&$args   last;
rewrite    /members/.*                   /member.php?$uri&$args         last;
rewrite    /blogs/.*                     /blog.php?$uri&$args           last;
rewrite    /entries/.*                   /entry.php?$uri&$args          last;
rewrite    ^/(?:(.*?)(?:/|$))(.*|$)$     /$1.php?r=$2                   last;

but am not having much luck. 404's everywhere, or images don't work, or something wonky. My vhost file is becoming a mess. Can someone with mod-rewrite urls working post their full vhost so I can see where to put everything?

Thanks!
