No *bling* for me. Starting compiz hangs machine

Moin, as I had some time yesterday, I did a fresh install of fc6 test3 on my IBM T40 - though I kept my /home partition. Eager to see the bling (which didn't work for me in the "XAir times" either) I ran gnome-window-decorator & compiz --replace gconf And *blam* - the machine shows a very short to none activity on disk and then hangs completely. Anyone else seeing this/being able to reproduce it? As the machine is not recoverable, I have no output from dmesg ...
