Matthew and Rui accepted or signed them off AFAIK.
On Peter's system (nokos@gmx.de, fujitsu with IGD support) it returns that
there is no video support which looks wrong.
I contacted him a bit late, after getting pointed to acpidump it still looks
odd/wrong, and I need acpi.debug_level=0x1f log_buf_len=16777216 output to
hopefully see what it is.

A comment from Andi/Len would be great.
Maybe this could already be sent to linux-next to make testing easier.

PS: and this is version 2, I already sent version 3 which had some cleanups.
