Yes if Mandriva provides developer packages in time? There is no official 
release of KDE4 yet, only snapshots. And you need Qt4.3 - not yet released, 
so you need qt-copy.
There is also mentioned the possibility to do a non-root installation of KDE4.
Perhaps in the next or the following week I will try to install a fresh KDE4 
and then I will tell you about my experience ;-)

Oh yes. I am really looking forward to delete some parts of the code and 
replace it with queued signals ;-) That's fun ;-))

http://websvn.kde.org/trunk/extragear/multimedia/amarok/ :
There is a CMakeLists.txt, and the code is Qt4. All Makefile.* are removed.
In the parent directory http://websvn.kde.org/trunk/extragear/multimedia/ 
there is also a CMakeLists.txt, and still a Makefile.cvs.

We have to talk to the other extragear applications about the location of the 
libraries that we share.
Again taking extragear/multimedia as an example, amarok/ is Qt4, while 
kmplayer/ is apparently not yet ported. So it seems to work. (I still have to 
read the documentation on CMake)
