i've written the "tostring" function so it does/should respect any 
colorkey. after you've got the image as a string, try this.

   imgstring = pygame.image.tostring(img_with_colorkey, "RGBA")
   print 'PIXEL:', [ord(x) for x in imgstring[:4]]

this will print you the RGBA values for the corner pixel. assuming it is 
"transparent" it should get you something like "PIXEL: [255, 0, 255, 0]"

maybe check some of the other pixels, and make sure the alpha value is 
"255" where you expect it to be?
