[Intel-gfx] Need to add a quirk to xserver-xorg-video-intel

[Gabriel M. Beddingfield]

Hello,

I'm needing to add a quirk to xf86-video-intel.  It looks 
like I can get the first two columns from lspci 
(chipType, subsysVendor == [VEND:CHIP])...

But I can't figure out how to get the number for subsysCard. 
(But I gather that I need to interpret `dmidecode` for this 
part.)

Thanks in advance!
