I have a new Macbookpro with Core i5 CPU. It contains Hybrid graphics
card. MAC does not expose Integrated Intel HD graphics card via
Bootcamp. Below is the information extracted after booting in to the
system via EFI, except the dmidecode output.

dmidecode (in BootCamp) : Product Name: MacBookPro6,2, System version
1.0

This output is after booting linux via EFI boot method.
00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 12)
01:00.0 VGA compatible controller [0300]: nVidia Corporation Device [10de:0a29] (rev a2)

attached DSDT.dsl is also from EFI boot method extracted using acpidump -a command and providing the RSD PTR address.
I also have dmesg output as well from EFI boot let me know if that's required. dmesg output shows that no output is connected to Intel HD graphics card.

** Attachment added: "DSDT from EFI boot method."
