After hours (and hours!) of git-bisecting, it said:

-----------------------
ccc7c28af205888798b51b6cbc0b557ac1170a49 is the first bad commit

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.
