because it's a name -> id mapping? It maps a short string like "skl" to
a single specific PCI ID... how useful is that and if we should retain
its behavior, I have dunno. But
i915_pciids.h doesn't have defines for individual PCI IDs, but groups of
them.

I would either have to create an accessor/iter for gen x in
intel_chipset.c or do some macros to extract the first id from the
i915_pciids.h, just to get an ID that is set in stone and change the
current id used :-/
