This version has some problem with the DRM but no CPU eater yet.

This version boots again just fine:

Linux zenogentoo 2.6.34-rc5-00059-gc2b4127 #105 SMP Fri Jul 16
11:13:21 CEST 2010 i686 Intel(R) Core(TM) i7 CPU 960 @ 3.20GHz
GenuineIntel GNU/Linux

As I understand I am bisecting upwards. Every time it does not boot
correctly I do

git bisect bad after the next boot.

Best
Zeno
