A few notes
* patch1 - it may be better to split the function to has_kms and
is_gpu_supported
* patch2 - introduced a minor memory leak, when has_kms fails
* patch3 - is ok
* patch4 - is incomplete, it turns out that we need to explicitly check
if IsSharable and SetShared() it. Note radeon and others would need a
similar fix. Intel is OK

I'm planning to consolidate the common parts of Nv{Pci,Platform}Probe()
into a common function, and send another series
