Fuli, when you say "In Fireworks it's a childs' play,... " are you talking about Fireworks MX??

If you want to IMPORT your Photoshop layers INTO Fireworks, version 4 handles it much better, though there are still problems with text. Simply choose EDIT > PREFERENCES then click on the Import tab. You can select different import options, but this should work for you.

If you want to perserve your layers FROM your Fireworks (4)file, INTO Photoshop, choose FILE > EXPORT, in the dialog box, name your file and choose Photoshop PSD from the Save As menu.

There are some other "export" settings to deal with in the "settings" menu. choose "options" and select the ones you want...

i can get more indepth if you want, but thats a good place to start. If you have an eariler version of Fireworks than 4, you will not be able to retain your layers. You can open you ".png" file in Photoshop but your wonderful layers are flattened!
