Many thanks an shame on me.
With correct spelling I can disable rc6 and power consumption goes 8
watts up. That's for sure not how it should be, so I removed the module
parameter again. But with 'drm.debug=0x2' it only reports:

[drm:intel_enable_rc6], RC6 enabled

so rc6p is not enabled if I understand right.

I am currently running kernel 3.2.32-1 from Sid and intend to run till I
get freezes.
