My original problem is solved: it turns out that I just needed to install NetworkManager-wifi rpm (which adds WiFi plugin to network manager). Now I'm back in happy GUI world in which everything "just works". Like on Macintosh... only better ;-) Valeri PS beats me why I needed to install it separately though, i.e. why it wasn't installed with "development workstation" (plus bunch of extras) rpm set...

Kernel is just a notch newer (3.13.0.24) which shouldn't matter according to Intel information which kernel versions this device is supported in. List of relevant kernel > modules loaded by ubuntu is exactly the same.
