With the five hotfixes applied it works for me.

But it fails to power down my system when shutting down.

It prints twice 'System halted' and blinks the keyboard leds, but does
not switch off. On all other kernel version I only see one keyboard
blink before the power goes out.

I compared its dmesg to vanilla-rc7 and -rc4-mm1, but expect that rc-4
assigns different IRQs I can't see any differences except the normal
variation in BogoMips etc.

As the system still responded to SysRq I got the following informations:
