(WW) intel(0): ESR is 0x00000011, page table error
(WW) intel(0): PGTBL_ER is 0x00040000, overlay tiling
(WW) intel(0): Existing errors found in hardware state.
i965 refers to the 'architecture family' whereas X3100 is a designator for a specific chip. However I can agree the naming gets confusing. Generally I pay attention to the architecture (i965, etc.) at a high level, and for the low level look at the PCI ID (visible in lspci -vvnn).
I notice in the Xorg.0.log, this warning:
