From the other mail:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=f892034a8ce80ed7098f667aae2eb6300e570603
is part of vanilla 2.6.35-rc4 and -rc5, but neither kernel works for
me.

After adding this to 2.6.35-rc5 the system boots and works so far.

But the CP is still broken:
