Wei, Ian --- are there any comments from the toolstack perspective?

So I looked again at commit 801d469ad8b2b88f669326327df03d03200efbfb
(which is the patch from Lenovo) and it only does 2 things (assuming I
parsed ASL correctly):
* Adds _PIC method
* Controls and describes legacy PCI interrupt routing. This
functionality has actually been moved into mk_dsdt.c and so this ASL
code is now generated.

Neither of these two things is used by libxl so technically we may not
need the ACK from Lenovo. OTOH, we may forget about this restriction in
the future and accidentally include those two later.
