Yes, KMS cannot be enabled in current 6.12 packages, we need a snapshot
of git master. I am thinking of working on this in the next days and
upload it to experimental.
Last time I tried, I had some problems with the radeon kernel driver
being loaded too late (see ). What do you use on Ubuntu in
/etc/modprobe.d/ or on the kernel command line ?
Ubuntu is putting radeon.ko (+drm.ko+ttm.ko+drmkmshelper.ko) to initrd and loading it early in the boot. I don't know the details how it is archived.
Reason for putting radeon.ko to initrd is to get flicker free booting with splash screen.
