i915 hardware support should be audited and momentarily disabled for some chipsets
The drm/i915 codebase has strong restrictions:
- generation 2/3/4/5 chipsets are likely not to work due to limitations in agpgart,
- generation 6/7 chipsets may not work properly due to hardware bugs not addressed in the driver,
- generation 8/9/10 chipsets will not work due to lack of support.
Therefore, while the xf86-video-intel module is up-to-date, problematic hardware will not work properly until the kernel driver is fixed.
Chipset are listed here and their status will be updated:
In the mean time, pci ids of considered adapters should be removed to allow fallback to vesa:

Removed pci ids for 2-5th generation from drm driver manifest in https://github.com/OpenIndiana/oi-userland/pull/2549, so that Xorg could fall back to vesa.
