In addition to the OpenChrome DRM/KMS driver hoping to be finally mainlined in 2022 for supporting aging VIA graphics hardware from the long-ago days of their x86 chipsets, separately there is a DRM/KMS kernel driver in the works for something even older.
.. A Linux DRM graphics driver for the Atari Falcon from the early 90';s.

Over the past two years a DRM driver has been in the works for the Atari graphics hardware with its built-in graphics chipset. This is not to be confused with the 2021-launched Atari VCS mini PC / game console, but the Atari Falcon personal computers out
of the Atari Corporation from the early 90';s that featured Motorola 68000 series processors and a programmable video controller.

It';s not yet in mainline, so it';ll be fun to see if Torvalds is up for including such an old and niche driver once it';s matured. I';ve always wanted an Atari Falcon, but they';re even more expensive than most other classic computers, so that';s most
likely never going to happen.
