Here you go:

Result:
http://blog.thepimp.net/public/images/gd/ttf/text_on_transparent_bgd.png

and the code:
http://cvs.php.net/viewvc.cgi/gd/playground/text_on_transparent_background/text_aa_alpha.c?revision=1.2&view=markup

Please remember that it will work for text but not other shapes. The
antialiased lines always blend on the destination pixel, for now.
