dmesg with acpiphp.disable=1

A quick search also showed this:
https://bugzilla.kernel.org/show_bug.cgi?id=67461

Good news: With acpiphp.disable=1 there are no errors with booting and using X.
In a tty the gpu is in DynOff state.



Not so good news: When starting X it switches to DynPwr and after several
minutes I don't think it ever powered down again. But when killing X it goes
back to DynOff.

Still bad news: rmmod radeon.
