I can definitely write a patch for that, it won't be worse that what we
have right now.  I wonder how we could handle the case when there's no
KMS for a particular hardware combination (if that's possible), since
kmscon requires that.  FTR, we require kmscon to be able to display
non-latin fonts such as CJK or arabic in the installer.

Now that I think about it, if we have a hard requirement on KMS, we
could just use a lightweight wayland compositor like cage to display the
installer, which would likely simplify the process since we'd have more
"usual" tools at our disposal.

Best,
