When I reverted this one from the gi-bisected tree, the box continued to 
boot (until it got stuck again during IDE/CDROM init, but that may be a 
different story). I'l; try to revert this from a vanilla 3.0-rc1 and see 
if it helps

Thanks,
Christian.

And then the system hangs, does not respond to keyboard (sysrq does not 
seem to work on this PowerBook G4). But after a while the system reboots 
itself, so I guess the machine panicked but did not print anything on the 
screen.
