It does work in 2.6.8 using backported patches (e.g. the debian 2.6.8 
kernel). But it doesn't work above that version because of other patches 
in arch/ppc/platforms/prep_pci.c and arch/ppc/platforms/prep_setup.c 
(made by Tom Rini?). I couldn't find out what exactly is causing this 
problem yet (because lack of time and the fact that my Powerstack is 
used as a router).
