[PATCH 07/14] drm/mgag200: Replace simple-KMS with regular atomic helpers

[kernel at linuxace.com]

I'm not sure if this information is useful, but we have found one system which
works with the 6.1 kernel.  I grabbed the lspci output from a working and
non-working system, pasted below.  Same kernel and same distro.
